มาแก้ทีละขั้น:

  1. กรกชมีเงิน 85 บาท ให้ขจร 15 บาท
    • เหลือเงิน = 85 - 15 = 70 บาท
  2. เงินที่เหลือ (70 บาท) = 1/3 ของขจร
    • ดังนั้น เงินขจร = 70 × 3 = 210 บาท
  3. ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท
    • เงินคิมหันต์ = 210 + 100 = 310 บาท
  4. เดิมกรกชมีเงิน 85 บาท
    • กรกชมีเงินน้อยกว่าคิมหันต์ = 310 - 85 = 225 บาท

ตัวเลือกที่ใกล้เคียงที่สุดคือ 210 บาท

{"correct_answer_key":"d"}

Let's solve this step by step:

  1. กรกช has 85 baht initially.
  2. After giving 15 baht to ขจร, กรกช has 85 - 15 = 70 baht.
  3. This amount (70 baht) is 1/3 of ขจร's money after receiving 15 baht. So ขจร has 70 × 3 = 210 baht after receiving the money.
  4. Before receiving the money, ขจร had 210 - 15 = 195 baht.
  5. We're told that ขจร has 100 baht less than คิมหันต์. So คิมหันต์ has 195 + 100 = 295 baht.
  6. The question asks how much less money กรกช has than คิมหันต์. กรกช has 85 baht, and คิมหันต์ has 295 baht. So กรกช has 295 - 85 = 210 baht less than คิมหันต์.
{"correct_answer_key":"d"}

Let's break down this problem step by step:

  1. Korakot (กรกช) has 85 baht initially.
  2. If Korakot gives 15 baht to Kajorn (ขจร), then Korakot will have 85 - 15 = 70 baht.
  3. After this transaction, Korakot's money is 1/3 of Kajorn's money. So Kajorn now has 70 × 3 = 210 baht.
  4. This means Kajorn received 15 baht from Korakot, so Kajorn initially had 210 - 15 = 195 baht.
  5. The problem also states that initially, Kajorn had 100 baht less than Kimmahun (คิมหันต์). So Kimmahun initially had 195 + 100 = 295 baht.
  6. We need to find how much less money Korakot initially had compared to Kimmahun. Korakot initially had 85 baht and Kimmahun had 295 baht. So Korakot had 295 - 85 = 210 baht less than Kimmahun.

Let's double-check this:

  • Korakot initially has 85 baht
  • Kajorn initially has 195 baht
  • Kimmahun initially has 295 baht
  • Korakot gives 15 baht to Kajorn, so Korakot now has 70 baht and Kajorn has 210 baht
  • 70 is indeed 1/3 of 210, so that part checks out
  • Kajorn initially has 195 baht, which is 100 baht less than Kimmahun's 295 baht, so that checks out
  • Korakot initially has 85 baht, which is 295 - 85 = 210 baht less than Kimmahun

So the answer is 210 baht, which corresponds to option D.

Actually, let me make sure I understood the problem correctly by translating it:

"Korakot has 85 baht. If he gives 15 baht to Kajorn, he will have 1/3 of what Kajorn has. If initially Kajorn had 100 baht less than Kimmahun, find how much less money Korakot initially had compared to Kimmahun."

Let me redo the calculation:

Let K = Korakot's initial money, which we know is 85 baht Let J = Kajorn's initial money, which we need to find Let H = Kimmahun's initial money, which we also need to find

After Korakot gives 15 baht to Kajorn:

  • Korakot has K - 15 = 85 - 15 = 70 baht
  • Kajorn has J + 15 baht

We're told that Korakot's money is now 1/3 of Kajorn's money: (K - 15) = (J + 15) / 3 70 = (J + 15) / 3 70 × 3 = J + 15 210 = J + 15 J = 195

So Kajorn initially had 195 baht.

We're also told that Kajorn initially had 100 baht less than Kimmahun: J = H - 100 195 = H - 100 H = 295

So Kimmahun initially had 295 baht.

How much less money did Korakot initially have compared to Kimmahun? H - K = 295 - 85 = 210 baht

So Korakot initially had 210 baht less than Kimmahun, which corresponds to option D.

Let me double-check my answer one more time:

  1. Korakot initially has 85 baht.
  2. Kajorn initially has 195 baht.
  3. Kimmahun initially has 295 baht.
  4. After Korakot gives 15 baht to Kajorn, Korakot has 70 baht and Kajorn has 210 baht.
  5. 70 is indeed 1/3 of 210, confirming our calculation.
  6. The difference between Kimmahun's and Korakot's initial money is 295 - 85 = 210 baht.

So the answer is 210 baht, which is option D.

This problem requires tracking initial and final amounts for three people (Korakot, Kajorn, and Kimmahun):

  1. Korakot initially has 85 baht.
  2. After giving 15 baht to Kajorn, Korakot has 70 baht.
  3. This amount (70 baht) is 1/3 of Kajorn's new amount, so Kajorn now has 210 baht.
  4. Kajorn received 15 baht, so initially had 195 baht.
  5. The problem states Kajorn had 100 baht less than Kimmahun, so Kimmahun had 295 baht.
  6. Therefore, Korakot (85 baht) initially had 295 - 85 = 210 baht less than Kimmahun.
{"correct_answer_key":"d"}

Let me solve this step by step.

Given information:

  • Korakot has 85 baht
  • If Korakot gives 15 baht to Khajorn, Korakot will have 1/3 of what Khajorn has
  • Originally, Khajorn has 100 baht less than Kimhan

Step 1: After giving 15 baht, Korakot has 85 - 15 = 70 baht

Step 2: Let's say Khajorn originally has x baht

  • After receiving 15 baht, Khajorn has x + 15 baht
  • According to the problem: 70 = (1/3)(x + 15)
  • Therefore: 210 = x + 15
  • So x = 195 baht (Khajorn's original amount)

Step 3: Since Khajorn originally has 100 baht less than Kimhan:

  • Kimhan has 195 + 100 = 295 baht

Step 4: The difference between Kimhan and Korakot:

  • 295 - 85 = 210 baht

Therefore, Korakot originally has 210 baht less than Kimhan.

{"correct_answer_key": "d"}

Let me translate and solve this Thai math problem step by step.

The problem says:

  • Korakot (กรกช) has 85 baht
  • If he gives Khajorn (ขจร) 15 baht, he will have 1/3 of what Khajorn has
  • Originally, Khajorn has 100 baht less than Kimhan (คิมหันต์)
  • Find how much less money Korakot originally has compared to Kimhan

Let me define variables:

  • Korakot has 85 baht
  • Let Khajorn originally have X baht
  • Let Kimhan have Y baht

After giving 15 baht to Khajorn:

  • Korakot has: 85 - 15 = 70 baht
  • Khajorn has: X + 15 baht

According to the problem: 70 = (1/3)(X + 15)

Solving for X: 70 = (X + 15)/3 210 = X + 15 X = 195

So Khajorn originally has 195 baht.

The problem states that Khajorn has 100 baht less than Kimhan: X = Y - 100 195 = Y - 100 Y = 295

So Kimhan has 295 baht.

The question asks how much less money Korakot has compared to Kimhan: Kimhan - Korakot = 295 - 85 = 210 baht

So the answer is 210, which is option d.

Let me solve this step by step.

Given information:

  • Korakot has 85 baht
  • If Korakot gives 15 baht to Khajorn, Korakot will have 1/3 of what Khajorn has
  • Originally, Khajorn has 100 baht less than Kimhan

After giving 15 baht:

  • Korakot has: 85 - 15 = 70 baht
  • Let Khajorn originally have X baht, so after receiving 15 baht: X + 15 baht

From the condition: 70 = (1/3)(X + 15) Solving: 210 = X + 15 Therefore: X = 195 baht (Khajorn's original amount)

Since Khajorn has 100 baht less than Kimhan: Kimhan has: 195 + 100 = 295 baht

The difference between Kimhan and Korakot: 295 - 85 = 210 baht

Let me solve this step by step.

Given information:

  • กรกช has 85 baht
  • กรกช gives ขจร 15 baht
  • After giving, กรกช's money = 1/3 of ขจร's money
  • Originally, ขจร had 100 baht less than คิมหันต์

Step 1: Find ขจร's money after receiving from กรกช After giving 15 baht, กรกช has: 85 - 15 = 70 baht Since กรกช's remaining money = 1/3 of ขจร's total money: 70 = (1/3) × ขจร's total money ขจร's total money = 70 × 3 = 210 baht

Step 2: Find ขจร's original money ขจร's original money = 210 - 15 = 195 baht

Step 3: Find คิมหันต์'s money Since ขจร originally had 100 baht less than คิมหันต์: คิมหันต์'s money = 195 + 100 = 295 baht

Step 4: Find the difference กรกช originally had 85 baht less than คิมหันต์: 295 - 85 = 210 baht

{"correct_answer_key":"d"}

Let me translate and solve this step by step.

The question is in Thai. Let me translate: "Korakot has 85 baht. If he gives 15 baht to Khajorn, he will have money equal to 1/3 of Khajorn's money. If originally Khajorn had 100 baht less than Kimhan, find how much less money Korakot originally had compared to Kimhan."

Let me define variables:

  • Let Korakot's original money = 85 baht (given)
  • Let Khajorn's original money = x baht
  • Let Kimhan's original money = y baht

From the problem:

  1. Korakot has 85 baht originally
  2. After giving 15 baht to Khajorn:
    • Korakot has: 85 - 15 = 70 baht
    • Khajorn has: x + 15 baht
  3. After the transaction, Korakot's money = 1/3 of Khajorn's money So: 70 = (1/3)(x + 15)
  4. Originally, Khajorn had 100 baht less than Kimhan So: x = y - 100

Let me solve equation from step 3: 70 = (1/3)(x + 15) 210 = x + 15 x = 195

So Khajorn originally had 195 baht.

From step 4: 195 = y - 100 y = 295

So Kimhan originally had 295 baht.

The question asks: How much less money did Korakot originally have compared to Kimhan? Kimhan's original money - Korakot's original money = 295 - 85 = 210 baht

So Korakot originally had 210 baht less than Kimhan.

Let me solve this step by step:

Given information:

  • Korakot originally has 85 baht
  • After giving 15 baht to Khajorn, Korakot's remaining money equals 1/3 of Khajorn's money
  • Originally, Khajorn had 100 baht less than Kimhan

Let Khajorn's original money = x baht

After the transaction:

  • Korakot has: 85 - 15 = 70 baht
  • Khajorn has: x + 15 baht

Since Korakot's money = 1/3 of Khajorn's money: 70 = (1/3)(x + 15) 210 = x + 15 x = 195 baht

So Khajorn originally had 195 baht.

Since Khajorn had 100 baht less than Kimhan: Kimhan's money = 195 + 100 = 295 baht

Therefore, Korakot had less money than Kimhan by: 295 - 85 = 210 baht

Let's break down the problem step by step.

  1. Initial Setup:

    • Let ( G ) be the amount of money กรกช (Gorkach) initially has.
    • Let ( K ) be the amount of money ขจร (Kachorn) initially has.
    • Let ( H ) be the amount of money คิมหันต์ (Kimhants) initially has.

  2. Given Information:

    • After กรกช gives 15 baht to ขจร, กรกช has ( \frac{1}{3} ) of ขจร's money.
    • ขจร initially has 100 baht less than คิมหันต์.

  3. Formulate Equations:

    • After giving 15 baht, กรกช has ( G - 15 ) baht.
    • After receiving 15 baht, ขจร has ( K + 15 ) baht.
    • The relationship between their amounts after the transaction is: [ G - 15 = \frac{1}{3}(K + 15) ]
    • The relationship between ขจร and คิมหันต์ is: [ K = H - 100 ]

  4. Solve the Equations:

    • Substitute ( K = H - 100 ) into the first equation: [ G - 15 = \frac{1}{3}((H - 100) + 15) ] Simplify: [ G - 15 = \frac{1}{3}(H - 85) ] Multiply both sides by 3: [ 3(G - 15) = H - 85 ] Expand and rearrange: [ 3G - 45 = H - 85 ] [ 3G - H = -40 ] [ H = 3G + 40 ]

  5. Use the Given Information:

    • We know กรกช initially has 85 baht after the transaction, so: [ G - 15 = \frac{1}{3}(K + 15) ] Substitute ( G = 85 + 15 = 100 ): [ 100 - 15 = \frac{1}{3}(K + 15) ] [ 85 = \frac{1}{3}(K + 15) ] Multiply both sides by 3: [ 255 = K + 15 ] [ K = 240 ]

  6. Find ( H ):

    • Substitute ( K = 240 ) into ( K = H - 100 ): [ 240 = H - 100 ] [ H = 340 ]

  7. Find the Difference:

    • The difference between คิมหันต์ and กรกช's initial amount: [ H - G = 340 - 100 = 240 ]

However, we need to find how much less กรกช initially had compared to คิมหันต์. Since กรกช initially had 100 baht (after giving 15 baht, he had 85 baht, so initially 100 baht), and คิมหันต์ had 340 baht, the difference is:

[ 340 - 100 = 240 ]

But the question asks for how much less กรกช initially had compared to คิมหันต์, which is:

[ 340 - 100 = 240 ]

However, the correct interpretation should be the difference between คิมหันต์ and กรกช's initial amount, which is:

[ 340 - 100 = 240 ]

Given the options, the closest and correct answer is:

{"correct_answer_key":"b"}

Note: The correct calculation should be ( 340 - 100 = 240 ), but since the options provided do not include 240, the closest logical answer based on the given options is 285, which suggests a possible typo in the problem or options. However, based on the provided options, the closest logical answer is:

{"correct_answer_key":"b"}

Let's break this problem down step by step to find the correct answer.

Problem Statement (Translated):

  • กรกช (Korakot) has 85 baht initially.
  • She gives ขจร (Kajor) 15 baht.
  • After giving, Korakot's money becomes 1/3 of Kajor's money.
  • Originally, Kajor had 100 baht less than คิมหันต์ (Kimhan).
  • Question: How much less money did Korakot originally have compared to Kimhan?

Step-by-Step Solution:

  1. Initial Amounts:

    • Korakot (K) = 85 baht
    • Kajor (J) = ?
    • Kimhan (H) = ?

  2. After Korakot gives 15 baht to Kajor:

    • Korakot's new amount = 85 - 15 = 70 baht
    • Kajor's new amount = J + 15

  3. Given that Korakot's money is now 1/3 of Kajor's: [ 70 = \frac{1}{3} (J + 15) ] [ J + 15 = 210 \quad (\text{Multiply both sides by 3}) ] [ J = 210 - 15 = 195 \quad (\text{Kajor's original money}) ]

  4. Kimhan's original money (H):

    • Kajor originally had 100 baht less than Kimhan: [ J = H - 100 ] [ 195 = H - 100 ] [ H = 295 \quad (\text{Kimhan's original money}) ]

  5. Difference between Korakot and Kimhan originally: [ H - K = 295 - 85 = 210 \quad \text{baht} ]

Final Answer:

Korakot originally had 210 baht less than Kimhan.

Explanation:

The problem is in Thai and involves finding how much less money Korkod (กรกช) originally has compared to Kimhan (คิมหันต์). The key steps are:

  1. Initial Setup:

    • Korkod originally has 85 baht.
    • Korkod gives 15 baht to Kajoran (ขจร), so Korkod now has (85 - 15 = 70) baht.
    • After receiving 15 baht, Kajoran has (K_j + 15) baht, where (K_j) is Kajoran's original money.

  2. Condition After Giving:

    • Korkod's money is now ( \frac{1}{3} ) of Kajoran's money: (70 = \frac{1}{3} (K_j + 15)).
    • Solving for (K_j): [ 70 \times 3 = K_j + 15 \implies 210 = K_j + 15 \implies K_j = 195 \text{ baht}. ]
    • So, Kajoran originally has 195 baht.

  3. Relationship with Kimhan:

    • Originally, Kajoran has 100 baht less than Kimhan: (K_j = K_h - 100), where (K_h) is Kimhan's original money.
    • Substituting (K_j = 195): [ 195 = K_h - 100 \implies K_h = 295 \text{ baht}. ]
    • Kimhan originally has 295 baht.

  4. Difference for Korkod:

    • Korkod originally has 85 baht, Kimhan has 295 baht.
    • The difference is (295 - 85 = 210) baht.
    • Thus, Korkod has 210 baht less than Kimhan originally.

The answer matches choice d.

The question is in Thai and translates to: "Korkot has 85 baht. If he gives 15 baht to Khachon, he will have 1/3 of Khachon's money. If originally Khachon had 100 baht less than Kimhun, how much less money did Korkot originally have than Kimhun?"

Here's the solution:

  1. After giving 15 baht: Korkot has 85 - 15 = 70 baht.
  2. Khachon's money after receiving 15 baht: Since Korkot has 1/3 of Khachon's money, Khachon has 70 * 3 = 210 baht.
  3. Khachon's original money: Before receiving 15 baht, Khachon had 210 - 15 = 195 baht.
  4. Kimhun's money: Khachon had 100 baht less than Kimhun, so Kimhun had 195 + 100 = 295 baht.
  5. Difference between Korkot's and Kimhun's original money: Kimhun had 295 baht and Korkot had 85 baht, so Korkot had 295 - 85 = 210 baht less.

Therefore, the answer is 210, corresponding to option d.

Let's break down the problem step by step:

  1. Kornkach's money after giving to Kajorn: Kornkach starts with 85 baht and gives 15 baht to Kajorn. So, Kornkach has 85 - 15 = 70 baht.

  2. Kajorn's money: After receiving 15 baht from Kornkach, Kajorn has three times the amount of money Kornkach has. So, Kajorn has 70 * 3 = 210 baht.

  3. Kajorn's original money: Kajorn received 15 baht from Kornkach, so originally Kajorn had 210 - 15 = 195 baht.

  4. Kimhant's original money: Kajorn originally had 100 baht less than Kimhant. So, Kimhant originally had 195 + 100 = 295 baht.

  5. The difference between Kornkach and Kimhant's original money: Kornkach originally had 85 baht, and Kimhant had 295 baht. The difference is 295 - 85 = 210 baht.

Therefore, Kornkach originally had 210 baht less than Kimhant.

Let's break down the problem step-by-step:

  1. Korakot's money after giving: Korakot starts with 85 baht and gives 15 baht to Khajorn. So, Korakot has 85 - 15 = 70 baht left.
  2. Khajorn's money after receiving: After the transaction, Korakot's money (70 baht) is 1/3 of Khajorn's money. Let X be Khajorn's initial money. Khajorn's money after receiving is X + 15. So, 70 = (1/3) * (X + 15) Multiply both sides by 3: 210 = X + 15 Solve for X: X = 210 - 15 = 195 baht. This means Khajorn originally had 195 baht.
  3. Kimhan's original money: Originally, Khajorn had 100 baht less than Kimhan. So, Kimhan's original money (H) was Khajorn's original money + 100. H = 195 + 100 = 295 baht.
  4. Difference between Korakot's and Kimhan's original money: We need to find how much less Korakot originally had than Kimhan. Difference = Kimhan's original money - Korakot's original money Difference = 295 - 85 = 210 baht.

The correct answer is 210 baht, which corresponds to option d.

{"correct_answer_key":"d"}

Here's a step-by-step breakdown of the problem:

  1. กรกช (Korakot) starts with 85 baht.
  2. กรกช gives 15 baht to ขจร (Khajorn).
    • กรกช now has 85 - 15 = 70 baht.
  3. After giving money, กรกช's money is 1/3 of ขจร's money.
    • This means ขจร's current money is 3 times กรกช's current money.
    • ขจร now has 70 * 3 = 210 baht.
  4. Calculate ขจร's original money.
    • ขจร received 15 baht from กรกช.
    • So, ขจร's original money was 210 - 15 = 195 baht.
  5. Originally, ขจร had 100 baht less than คิมหันต์ (Kimhan).
    • This means คิมหันต์'s original money was ขจร's original money + 100 baht.
    • คิมหันต์ originally had 195 + 100 = 295 baht.
  6. Find how much less กรกช originally had than คิมหันต์.
    • กรกช originally had 85 baht.
    • คิมหันต์ originally had 295 baht.
    • The difference is 295 - 85 = 210 baht.

Therefore, กรกช originally had 210 baht less than คิมหันต์.

This is a word problem in Thai. Let's break it down:

  1. After giving money: Krokach has 85 - 15 = 70 baht.
  2. Khajorn's money: Krokach's remaining money (70 baht) is 1/3 of Khajorn's money. Therefore, Khajorn has 70 * 3 = 210 baht.
  3. Kimhan's money: Khajorn has 100 baht less than Kimhan. So, Kimhan has 210 + 100 = 310 baht.
  4. Difference between Krokach and Kimhan: Originally, Krokach had 85 baht. Kimhan has 310 baht. The difference is 310 - 85 = 225 baht. However, the question asks for the original difference. We need to account for the 15 baht Krokach gave to Khajorn. Krokach originally had 85 baht, and Kimhan had 310 baht. The difference is 310 - 85 = 225. This isn't one of the options. Let's re-examine the problem.

The question asks how much less Krokach had than Kimhan originally. Krokach started with 85 baht. Khajorn ended up with 210 baht after receiving 15 baht from Krokach. Kimhan had 100 baht more than Khajorn, so Kimhan had 210 + 100 = 310 baht. The difference between Kimhan and Krokach is 310 - 85 = 225. Still not an option.

Let's try setting up equations:

  • Let K = Krokach's original money (85)
  • Let X = Khajorn's original money
  • Let M = Kimhan's original money

We know:

  • K - 15 = (1/3)X => 85 - 15 = (1/3)X => 70 = (1/3)X => X = 210
  • X = M - 100 => 210 = M - 100 => M = 310
  • We want to find M - K = 310 - 85 = 225.

Still not an option. Let's re-read the question carefully. It states "เดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท" which translates to "How much less money did Krokach have than Kimhan originally?".

Let's consider the possibility of a misinterpretation. The 1/3 relationship applies after the transfer. So, Krokach has 70 baht, which is 1/3 of Khajorn's money. Khajorn has 210. Kimhan has 100 more than Khajorn, so Kimhan has 310. The difference between Kimhan and Krokach is 310 - 85 = 225.

Since 225 isn't an option, let's look for a possible error in the problem or the options. The closest answer is 210. Let's see if we can work backwards to get that.

If the answer is 210, then Kimhan had 85 + 210 = 295. Then Khajorn had 295 - 100 = 195. Krokach had 70, which is 1/3 of 210. This doesn't fit.

Let's try to find an error in the problem statement. If Krokach had 85 and gave 15, he had 70. This is 1/3 of Khajorn's money, so Khajorn had 210. Khajorn had 100 less than Kimhan, so Kimhan had 310. The difference is 310 - 85 = 225.

Given the options, the closest answer is 'a' 295. Let's assume the problem meant to ask how much more Kimhan had than Krokach after the transfer. Krokach had 70, Kimhan had 310. 310 - 70 = 240. Still not an option.

I suspect there's an error in the problem or the answer choices. However, based on the given information, the closest answer is 'a' 295, assuming a slight misinterpretation of the question.

คำอธิบาย:
กรกชมีเงิน 85 บาท ให้ขจร 15 บาท เหลือ 70 บาท
หลังจากนั้น เงินของกรกช (70 บาท) = 1/3 ของขจร
ดังนั้น ขจรมีเงิน 70 × 3 = 210 บาท (หลังจากได้รับ 15 บาท)
แปลว่า ขจรเดิมมีเงิน 210 - 15 = 195 บาท

ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท
ดังนั้น คิมหันต์มีเงิน 195 + 100 = 295 บาท

กรกชเดิมมีเงิน 85 บาท
ดังนั้น เดิมกรกชมีเงินน้อยกว่าคิมหันต์ 295 - 85 = 210 บาท

{"correct_answer_key":"d"}

Let's analyze the problem step-by-step:

  • Let the amount of money ขจร originally has be ( x ) baht.
  • กรกช has 85 baht.
  • If กรกช gives 15 baht to ขจร, then:
    • กรกช will have ( 85 - 15 = 70 ) baht.
    • ขจร will have ( x + 15 ) baht.
  • According to the problem, after this transaction, กรกช's money is ( \frac{1}{3} ) of ขจร's money: [ 70 = \frac{1}{3}(x + 15) ]
  • Multiply both sides by 3: [ 210 = x + 15 ]
  • Solve for ( x ): [ x = 210 - 15 = 195 ]
  • So, ขจร originally has 195 baht.
  • The problem states that ขจร originally has 100 baht less than คิมหันต์: [ \text{คิมหันต์} = x + 100 = 195 + 100 = 295 ]
  • Finally, we want to find how much less money กรกช originally has compared to คิมหันต์: [ 295 - 85 = 210 ]

Therefore, กรกช originally has 210 baht less than คิมหันต์.

{"correct_answer_key":"d"}

กรกชมีเงิน 85 บาท ให้ขจรไป 15 บาท ทำให้เงินของกรกชเหลือ 70 บาท ขณะเดียวกัน เงินของขจรจะเป็น 15 + (เงินที่ได้รับ) ซึ่งหลังจากนั้น เงินของกรกชเป็น 1/3 ของขจร ดังนั้น:

สมมติว่าเงินของขจรหลังให้คือ ( x ) บาท เงินของกรกชหลังให้คือ 70 บาท จากโจทย์: ( 70 = \frac{1}{3} x \Rightarrow x = 210 )

ดังนั้น เงินของขจรหลังให้คือ 210 บาท ซึ่งก่อนให้ขจรไป 15 บาท ขจรมีเงิน ( 210 - 15 = 195 ) บาท

นอกจากนี้ ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ดังนั้น: เงินของคิมหันต์ = 195 + 100 = 295 บาท

สุดท้าย ต้องการหาว่าเดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท: เงินของคิมหันต์ - เงินของกรกชเดิม = 295 - 85 = 210 บาท

แต่เนื่องจากคำถามถามว่า "เดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท" คำตอบคือ 210 บาท

{"correct_answer_key":"d"}

Let's solve step by step:

  1. กรกช initially has 85 baht. After giving ขจร 15 baht, กรกช has 85 - 15 = 70 baht.
  2. After receiving 15 baht, ขจร has an unknown amount, but we know กรกช's new amount (70 baht) is exactly 1/3 of ขจร's new amount. Thus, ขจร now has 70 × 3 = 210 baht.
  3. Before receiving 15 baht, ขจร had 210 - 15 = 195 baht.
  4. Initially, ขจร had 100 baht less than คิมหันต์. Therefore, คิมหันต์ initially had 195 + 100 = 295 baht.
  5. Initially, กรกช had 85 baht, and คิมหันต์ had 295 baht. Thus, กรกช initially had 295 - 85 = 210 baht less than คิมหันต์.

The correct answer is 210 baht, corresponding to option "d".

{"correct_answer_key":"d"}

To solve this problem, we need to determine how much less money Korakot originally had compared to Kimhan.

  1. Korakot has 85 baht and gives 15 baht to Khajorn, leaving him with 70 baht.
  2. After giving 15 baht, Korakot's remaining money (70 baht) is 1/3 of Khajorn's total money.
  3. Therefore, Khajorn's total money is 70 * 3 = 210 baht.
  4. Originally, Khajorn had 210 - 15 = 195 baht.
  5. Khajorn originally had 100 baht less than Kimhan, so Kimhan had 195 + 100 = 295 baht.
  6. Korakot originally had 85 baht, which is 295 - 85 = 210 baht less than Kimhan.

Thus, Korakot originally had 210 baht less than Kimhan.

{"correct_answer_key":"d"}

จากข้อมูลที่ให้มา กรกชมีเงิน 85 บาท ถ้าให้ขจรไป 15 บาท เขาจะมีเงินเหลือ 70 บาท (85 - 15 = 70) และเงินของขจรจะเป็น 3 เท่าของเงินที่กรกชมีหลังจากให้เงินไป ดังนั้น ขจรจะมีเงิน 70 * 3 = 210 บาท

เนื่องจากขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ดังนั้น คิมหันต์จะมีเงิน 210 + 100 = 310 บาท

สุดท้าย กรกชมีเงิน 85 บาท ดังนั้นเขามีเงินน้อยกว่าคิมหันต์ 310 - 85 = 225 บาท

แต่ในตัวเลือกไม่มีคำตอบที่ตรงกับ 225 บาท ดังนั้นเราต้องหาค่าที่ใกล้เคียงที่สุดในตัวเลือกที่ให้มา

จากตัวเลือกที่มีอยู่ ค่าที่ใกล้เคียงที่สุดคือ 210 บาท

Let's, let's solve this step by step. We are tasked with finding out how much less money กรกช (Korkot) originally has compared to คิมหันต์ (Kimhant), given some conditions about money transactions and relationships.

  1. กรกช starts with 85 บาท and gives 15 บาท to ขจร (Khajon), leaving กรกช with 85 - 15 = 70 บาท.
  2. After this transaction, กรกช's money (70 บาท) is 1/3 of ขจร's money. So, ขจร must have 70 * 3 = 210 บาท after receiving the 15 บาท.
  3. Since กรกช gave 15 บาท to ขจร, ขจร originally had 210 - 15 = 195 บาท.
  4. It's given that originally, ขจร has 100 บาท less than คิมหันต์. So, คิมหันต์ originally has 195 + 100 = 295 บาท.
  5. Finally, we need to find how much less กรกช originally has compared to คิมหันต์. That is 295 - 85 = 210 บาท.

Thus, the answer is 210 บาท, which corresponds to option D.

{"correct_answer_key":"d"}

First, the question is in Thai. Let me translate it to understand it properly:

"กรกชมีเงิน 85 บาท ถ้าให้ขจรไป 15 บาท เขาจะมีเงินเป็น 1/3 ของขจร ถ้าเดิมขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท จงหาว่าเดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท"

Breaking it down:

  • กรกช (Korkach) has 85 baht.

  • If he gives 15 baht to ขจร (Khachon), then Korkach will have 1/3 of what Khachon has.

  • Originally, Khachon has 100 baht less than คิมหันต์ (Kimhant).

  • We need to find out how much less than Kimhant did Korkach originally have.

So, let's define variables:

  • Let K be the original amount Khachon has.

  • Let M be the original amount Kimhant has.

From the question: Originally, Khachon has 100 baht less than Kimhant, so:

K = M - 100

Korkach originally has 85 baht.

If Korkach gives 15 baht to Khachon, then:

Korkach's new amount: 85 - 15 = 70 baht.

After this, Korkach's amount is 1/3 of Khachon's new amount.

Khachon's new amount: Original K + 15 baht.

So, 70 = (1/3) * (K + 15)

Let me write that equation:

70 = \frac{1}{3} (K + 15)

Multiply both sides by 3:

210 = K + 15

So, K = 210 - 15 = 195 baht.

K = 195 baht (original amount for Khachon)

Now, since K = M - 100,

195 = M - 100

M = 195 + 100 = 295 baht.

Originally, Korkach has 85 baht, and Kimhant has 295 baht.

So, Korkach has less than Kimhant by: 295 - 85 = 210 baht.

The question is: "เดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท" which means "Originally, how many baht less than Kimhant did Korkach have?"

Yes, so 295 - 85 = 210 baht less.

Looking at the options: a:295, b:285, c:250, d:210, e:195

So, d:210 is the answer.

Double-checking my calculations:

  1. Korkach after giving: 85 - 15 = 70 baht.

  2. This is 1/3 of Khachon's new amount: 70 = (1/3)(K + 15)

  3. 70 * 3 = K + 15 → 210 = K + 15 → K = 195

  4. K = M - 100 → 195 = M - 100 → M = 295

  5. Difference: M - Korkach's original = 295 - 85 = 210

Yes, that seems correct.

So, the correct answer is d:210.

Explanation:

คำถามนี้เกี่ยวกับการแก้โจทย์คณิตศาสตร์ที่เกี่ยวข้องกับจำนวนเงินของบุคคลสามคน: กรกช, ขจร, และคิมหันต์ โดยสรุปดังนี้:

  • กรกชมีเงิน 85 บาทเดิม และให้ขจรไป 15 บาท ทำให้กรกชเหลือ 70 บาท ซึ่งเท่ากับ 1/3 ของเงินที่ขจรมีหลังได้รับเงินนั้น
  • จากนั้น ทราบว่าขจรมีเงินน้อยกว่าคิมหันต์ 100 บาทเดิม

จากการคำนวณ:

  • ให้ ( K ) เป็นจำนวนเงินเดิมของขจร
  • หลังกรกชให้เงิน 15 บาท ขจรจะมี ( K + 15 ) บาท และ 70 = (\frac{1}{3}(K + 15))
  • แก้สมการ: ( 70 \times 3 = K + 15 ) → ( 210 = K + 15 ) → ( K = 195 ) บาท
  • ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ดังนั้น คิมหันต์มี ( 195 + 100 = 295 ) บาท
  • เดิมกรกชมี 85 บาท และน้อยกว่าคิมหันต์ ( 295 - 85 = 210 ) บาท

ดังนั้น คำตอบที่ถูกต้องคือตัวเลือก d: 210

Breaking it down:

  • กรกช (Grorkot) has 85 baht.

  • If he gives 15 baht to ขจร (Khajon), then Grorkot will have 1/3 of what Khajon has.

  • Originally, Khajon has 100 baht less than คิมหันต์ (Kimharn).

  • We need to find out how much less than Kimharn Grorkot originally has.

Let’s define variables:

  • Let G be the original amount Grorkot has: G = 85 baht.

  • Let K be the original amount Khajon has.

  • Let M be the original amount Kimharn has.

From the question:

  1. After Grorkot gives 15 baht to Khajon:

    • Grorkot has: 85 - 15 = 70 baht.

    • Khajon has: K + 15 baht.

    And at this point, Grorkot's amount is 1/3 of Khajon's amount:

    So, 70 = (1/3) * (K + 15)

  2. Originally, Khajon has 100 baht less than Kimharn:

    So, K = M - 100

  3. We need to find how much less than Kimharn Grorkot originally has, which is M - G = M - 85.

First, solve for K from the equation:

70 = (1/3) * (K + 15)

Multiply both sides by 3: 210 = K + 15

So, K = 210 - 15 = 195 baht.

K = 210 - 15? Wait, no:

210 = K + 15

K = 210 - 15 = 195 baht. Yes.

Khajon originally has 195 baht.

Khajon has 100 baht less than Kimharn, so:

K = M - 100

195 = M - 100

M = 195 + 100 = 295 baht.

Grorkot originally has 85 baht, so how much less than Kimharn: M - G = 295 - 85 = 210 baht less.

The question is: "เดิมกรกชมีเงินน้อยกว่าคิมหันต์กี่บาท" which means "Originally, how many baht less than Kimharn does Grorkot have?"

So, 295 - 85 = 210 baht less.

Looking at the options: a:295, b:285, c:250, d:210, e:195

So, d:210

Double-check:

Grorkot: 85

Gives 15 to Khajon: Grorkot now has 70.

Khajon originally: K

Khajon now: K + 15

70 = (1/3)(K + 15)

210 = K + 15

K = 195

Khajon = Kimharn - 100

195 = M - 100

M = 295

Grorkot less than Kimharn: 295 - 85 = 210

Yes, correct.

So, the correct answer is d:210

Let's solve this step by step.

  • กรกช (Krokot) starts with 85 บาท and gives 15 บาท to ขจร (Khajon), leaving Krokot with 85 - 15 = 70 บาท.
  • After receiving 15 บาท, Khajon's money becomes 1/3 of Krokot's remaining money. Since Krokot has 70 บาท, Khajon's money must be 70 * 3 = 210 บาท.
  • Before receiving the 15 บาท, Khajon had 210 - 15 = 195 บาท.
  • It is given that originally, Khajon had 100 บาท less than คิมหันต์ (Kimhant). So, Kimhant originally had 195 + 100 = 295 บาท.
  • The question asks how much less money Krokot originally had compared to Kimhant. Krokot originally had 85 บาท, and Kimhant had 295 บาท, so the difference is 295 - 85 = 210 บาท.

  2. หลังจากให้เงินขจรไป 15 บาท กรกชมี 70 บาท และขจรมี 1/3 ของกรกชที่เหลืออยู่ ซึ่งหมายความว่าขจรมี 3 เท่าของกรกชที่เหลืออยู่

ให้ x เป็นจำนวนเงินที่ขจรมี ดังนั้น กรกชมี 70 บาท และขจรมี 3 เท่าของ 70 บาท คือ 3 * 70 = 210 บาท

  1. เดิมขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ดังนั้น เดิมกรกชมีเงินน้อยกว่าคิมหันต์ 210 - 85 = 125 บาท แต่คำถามถามว่าน้อยกว่ากี่บาท ซึ่งหมายความว่าเราต้องดูว่าถ้ากรกชมี 85 บาท และคิมหันต์มีเงินมากกว่ากรกช 125 + 100 = 225 บาท แต่ 225 ไม่ใช่คำตอบที่เราต้องการ เราต้องการหาว่า กรกชมีเงินน้อยกว่าคิมหันต์กี่บาท

คำตอบที่ถูกคือ 285 - 85 = 200 เงินที่กรกชมี 200 บาท แต่ คำตอบ 285 ตรงกับ c

{"correct_answer_key":"c"}

To solve this problem, let's break it down step by step:

  1. กรกชมีเงิน 85 บาท (K has 85 baht).
  2. กรกให้ขจร 15 บาท (K gives J 15 baht).
  3. กรกมีเงินเป็น 1/3 ของขจร (K has 1/3 of J's money).

Let's denote the amount of money K has after giving 15 baht to J as ( K' ) and the amount of money J has as ( J ).

So, ( K' = 85 - 15 = 70 ) baht.

Since K has 1/3 of J's money, we can write: [ K' = \frac{1}{3} J ]

Substituting ( K' ) with 70: [ 70 = \frac{1}{3} J ] [ J = 70 \times 3 = 210 ]

So, J has 210 baht after receiving 15 baht from K.

Now, let's find out how much money J had originally: [ J_{\text{original}} = 210 - 15 = 195 ]

Since J originally had 195 baht and this is 100 baht less than คิมหันต์ (let's denote คิมหันต์ as ( C )): [ J_{\text{original}} = C - 100 ] [ 195 = C - 100 ] [ C = 195 + 100 = 295 ]

Finally, we need to find out how much less money K had originally compared to C: [ K_{\text{original}} = 85 ] [ C = 295 ] [ \text{Difference} = C - K_{\text{original}} = 295 - 85 = 210 ]

So, the correct answer is 210 baht.

  2. After giving away 15 baht, Grksom has ( G - 15 ) baht left, which is 1/3 of Khjr's original amount: ( G - 15 = \frac{1}{3}K )

Now we can substitute ( K ) from the first equation into the second equation: [ G - 15 = \frac{1}{3}(G + 100) ]

To solve for ( G ), we first eliminate the fraction by multiplying both sides by 3: [ 3(G - 15) = G + 100 ] [ 3G - 45 = G + 100 ]

Next, we isolate ( G ) by moving all terms involving ( G ) to one side and constants to the other side: [ 3G - G = 100 + 45 ] [ 2G = 145 ] [ G = 72.5 ]

So, Grksom originally had 72.5 baht. To find out how much less this is compared to Khjr: [ K = G + 100 = 72.5 + 100 = 172.5 ] [ \text{Difference} = K - G = 172.5 - 72.5 = 100 ]

{"correct_answer_key":"d"}

Let's break down the problem step by step:

  1. Initial Information:

    • Krok has 85 baht.
    • If Krok gives 15 baht to Khot, Krok will have 70 baht left.
    • After giving 15 baht, Krok’s remaining money (70 baht) is 1/3 of Khot’s money.

  2. Finding Khot’s Money:

    • If 70 baht is 1/3 of Khot’s money, then Khot’s money is ( 70 \times 3 = 210 ) baht.

  3. Relationship Between Khot and Kimhan:

    • Khot has 100 baht less than Kimhan.
    • Therefore, Kimhan has ( 210 + 100 = 310 ) baht.

  4. Difference Between Krok and Kimhan:

    • Krok initially has 85 baht.
    • The difference between Krok and Kimhan is ( 310 - 85 = 225 ) baht.

However, the options provided do not match this calculation directly. Let's re-evaluate the problem constraints and options to ensure accuracy.

Given the options, the correct calculation should align with the provided answers. The correct difference should be 210 baht.

คำอธิบายโดยย่อ:

  1. กรกชมี 85 บาท และเมื่อให้ขจร 15 บาท จะเหลือ 70 บาท
  2. 70 บาทนี้เท่ากับ 1/3 ของเงินขจรในตอนนั้น แสดงว่าเงินขจรหลังรับ 15 บาท คือ 210 บาท (70 × 3) ดังนั้นขจรเดิมมี 195 บาท
  3. ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท => คิมหันต์มี 295 บาท
  4. กรกชมี 85 บาท จึงน้อยกว่าคิมหันต์ 295 - 85 = 210 บาท

Korakot starts with 85 ฿.
After giving Khajon 15 ฿ he has 70 ฿ left, which equals one‑third of Khajon’s new amount:

70 = (Khajon_initial + 15)/3
⇒ Khajon_initial = 195 ฿.

Khajon originally had 100 ฿ less than Kimhan, so

Kimhan_initial = 195 + 100 = 295 ฿.

Korakot originally had 85 ฿, therefore he had

295 − 85 = 210 ฿

less than Kimhan. That matches choice d.

{"correct_answer_key":"d"}

กรกชมี 85 บาท
หลังจากให้ขจร 15 บาท เขาจะเหลือ 70 บาท
ขณะนั้น 70 บาทเป็น 1/3 ของเงินขจร ⇒ เงินขจรหลังรับ = 70 × 3 = 210 บาท
ดังนั้นเงินขจรเดิม = 210 – 15 = 195 บาท
ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ⇒ เงินคิมหันต์ = 195 + 100 = 295 บาท
กรกชเดิมมีน้อยกว่าคิมหันต์ = 295 – 85 = 210 บาท

{"correct_answer_key":"d"}

เมื่อกรกชให้ขจร 15 บาท จะเหลือ 85 − 15 = 70 บาท ซึ่งเป็น 1/3 ของเงินขจรหลังรับเงิน
⇒ เงินขจรหลังรับ = 3 × 70 = 210 บาท
เงินขจรก่อนรับ = 210 − 15 = 195 บาท

ขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท
⇒ เงินคิมหันต์ = 195 + 100 = 295 บาท

กรกชมีเงินน้อยกว่าคิมหันต์ = 295 − 85 = 210 บาท

{"correct_answer_key":"d"}

After the transaction, กรกช will have 85 - 15 = 70 baht, and ขจร will have his original amount plus 15, which we'll call x + 15. Since 70 = 1/3(x + 15), solving gives x = 195 baht for ขจร originally. Knowing that ขจร originally had 100 baht less than คิมหันต์, it means คิมหันต์ had 195 + 100 = 295 baht originally. The difference between คิมหันต์’s and กรกช’s money is 295 - 85 = 210 baht.

{"correct_answer_key": "d"}

After receiving 15 baht, the money of กรกช becomes 85 – 15 = 70 baht. According to the condition, 70 baht is 1/3 of ขจร’s money after getting 15 baht, meaning:

  70 = 1/3 × (ขจร's original money + 15)

Multiplying both sides by 3:   210 = ขจร's original money + 15

Thus, ขจร's original money = 210 – 15 = 195 baht.

Since originally ขจร had 100 baht less than คิมหันต์, คิมหันต์ had:   195 + 100 = 295 baht.

The difference between คิมหันต์ and กรกช originally is:   295 – 85 = 210 baht.

This corresponds to option D.

{ "correct_answer_key": "d" }

Initially, กรกช (with 85 baht) gives ขจร 15 baht. So after this transaction, กรกช will have 85 - 15 = 70 baht. According to the problem, this 70 baht equals 1/3 of the money that ขจร has after receiving the 15 baht. Let x be ขจร’s original money. Then after receiving 15 baht, ขจร has x + 15. Thus, we have:

  70 = (1/3) × (x + 15)

Multiplying both sides by 3:

  210 = x + 15
  x = 210 - 15 = 195 baht

The problem also states that originally ขจร had 100 baht less than คิมหันต์. So คิมหันต์ originally had:

  195 + 100 = 295 baht

Therefore, the difference between คิมหันต์’s and กรกช’s original money is:

  295 - 85 = 210 baht

So กรกช originally had 210 baht less than คิมหันต์.

{"correct_answer_key":"d"}

Let's break down the problem step by step:

  1. Initial Information:

    • กรกช (Korak) has 85 บาท.
    • He gives 15 บาท to ขจร (Kachorn), so he has (85 - 15 = 70) บาท left.

  2. Condition Given:

    • After giving 15 บาท, กรกช has 1/3 of ขจร's money.
    • Let (x) be the amount of money ขจร had initially.
    • After receiving 15 บาท, ขจร has (x + 15) บาท.
    • According to the condition: [ 70 = \frac{1}{3}(x + 15) ]
    • Solving for (x): [ 70 \times 3 = x + 15 \ 210 = x + 15 \ x = 210 - 15 \ x = 195 ]

  3. Comparison with คิมหันต์ (Kimhan):

    • ขจร initially had 195 บาท, which is less than คิมหันต์'s 100 บาท.
    • Therefore, คิมหันต์ has more than 195 บาท.

  4. Finding the Difference:

    • คิมหันต์ has more than 195 บาท, so let's assume คิมหันต์ has 295 บาท (since ขจร has less than คิมหันต์ and ขจร has 195 บาท).
    • The difference between คิมหันต์ and กรกช is: [ 295 - 85 = 210 ]

Thus, กรกชมีเงินน้อยกว่าคิมหันต์ 210 บาท, which corresponds to option D.

{"correct_answer_key":"d"}

To solve this problem, let's break it down step by step:

Step 1: Define variables

  • Let K represent the amount of money ขจร (Kajorn) originally had.
  • Let C represent the amount of money คิมหันต์ (Kimhan) originally had.
  • กรกช (Grakach) originally has 85 baht.

Step 2: Analyze the transaction

  • If กรกช gives 15 baht to ขจร:
    • กรกช will have $ 85 - 15 = 70 $ baht.
    • ขจร will then have $ K + 15 $ baht.
  • After this transaction, it is stated that กรกช will have 1/3 of the money that ขจร has: $$ 70 = \frac{1}{3}(K + 15) $$

Step 3: Solve for $ K $

Multiply through by 3 to eliminate the fraction: $$ 3 \cdot 70 = K + 15 $$ $$ 210 = K + 15 $$ $$ K = 195 $$

Thus, ขจร originally had 195 baht.

Step 4: Relate ขจร and คิมหันต์

It is given that ขจร originally had 100 baht less than คิมหันต์: $$ C = K + 100 $$ Substitute $ K = 195 $: $$ C = 195 + 100 = 295 $$

So, คิมหันต์ originally had 295 baht.

Step 5: Calculate how much less กรกช had compared to คิมหันต์

กรกช originally had 85 baht, and คิมหันต์ had 295 baht. The difference is: $$ 295 - 85 = 210 $$

Final Answer:

กรกช originally had 210 baht less than คิมหันต์.

{"correct_answer_key":"d"}

กรกชมีเงินเริ่มต้น 85 บาท หลังจากให้ขจร 15 บาท จะเหลือ 70 บาท ซึ่งเป็น 1/3 ของเงินขจรหลังรับเพิ่ม 15 บาท ดังนั้นเงินขจรหลังรับเพิ่มคือ 210 บาท หรือ $ x + 15 = 210 $ ทำให้ขจรเริ่มต้นมี 195 บาท แต่ขจรมีน้อยกว่าคิมหันต์ 100 บาท ดังนั้นคิมหันต์มี $ 195 + 100 = 295 $ บาท เดิมกรกชมีน้อยกว่าคิมหันต์ $ 295 - 85 = 210 $ บาท

Okay, let's tackle this problem step by step. First, I need to understand what's being asked here. The question is in Thai, so I'll translate it to make sure I get all the details right.

The problem says: "Korkkam has 85 baht. If she gives Chot 15 baht, then her money will be 1/3 of Chot's. Originally, Chot had 100 baht less than Khimanth. Find how much less money Korkkam originally had compared to Khimanth."

Alright, let's break this down. Let me assign variables to each person's original amount of money to make it easier.

Let me denote:

  • Let K be the original amount Korkkam has. According to the problem, K is 85 baht. Wait, the problem says Korkkam has 85 baht, so K = 85. But maybe I need to confirm that. Wait, the first sentence says "Korkkam has 85 baht", so that's her current amount? Or is that her original amount? Hmm, the problem says "เดิมขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท" which translates to "Originally, Chot had 100 baht less than Khimanth." So the problem is asking for the original difference between Korkkam and Khimanth. So the 85 baht Korkkam has is her original amount? Probably yes, since the problem starts by stating that. So Korkkam's original money is 85 baht.

Wait, but the problem says "ถ้าให้ขจรไป 15 บาท เขาจะมีเงินเป็น 1/3 ของขจร" which translates to "If she gives Chot 15 baht, then her money will be 1/3 of Chot's." So this is a conditional scenario. So after giving 15 baht to Chot, Korkkam's remaining money is 1/3 of Chot's money at that point.

Let me define variables properly:

Let me denote:

  • Korkkam's original money: K = 85 baht (given)
  • Chot's original money: C
  • Khimanth's original money: Kh

The problem states that originally, Chot had 100 baht less than Khimanth, so C = Kh - 100. We need to find how much less Korkkam had than Khimanth originally, which is Kh - K. Since K is 85, we need to find Kh - 85.

Now, the key part is the conditional scenario where Korkkam gives 15 baht to Chot. After this transaction:

  • Korkkam's money becomes K - 15 = 85 -15 = 70 baht.
  • Chot's money becomes C + 15 baht.

According to the problem, after this transaction, Korkkam's money is 1/3 of Chot's. So:

70 = (1/3)(C + 15)

We can solve for C here.

Multiply both sides by 3:

210 = C + 15

Subtract 15:

C = 210 -15 = 195

So Chot originally had 195 baht.

But we know that Chot's original money C is 100 less than Khimanth's, so:

C = Kh - 100

195 = Kh - 100

Therefore, Kh = 195 + 100 = 295

Now, the question is asking how much less Korkkam had than Khimanth originally. Korkkam had 85, Khimanth had 295, so the difference is 295 -85 = 210 baht.

Wait, but looking at the options given: a is 295, b 285, c 250, d 210, e 195. So 210 is option d. Hmm, but let me double-check my steps to be sure.

Wait, let me go through again:

Original amounts: Korkkam (K) = 85 Chot (C) = ? Khimanth (Kh) = C + 100 (since Chot had 100 less than Khimanth, so Kh = C +100)

After Korkkam gives 15 to Chot: Korkkam has 85-15=70 Chot has C +15

The condition is 70 = (1/3)(C +15) Multiply both sides by 3: 210 = C +15 → C = 195

Thus Khimanth has 195 +100 = 295

Difference between Khimanth and Korkkam is 295 -85 = 210. So the answer is d) 210.

Wait, but let me check if I interpreted the problem correctly. The problem says "เดิมขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท" which translates to "Originally, Chot had 100 baht less than Khimanth." So yes, that's C = Kh -100 → Kh = C +100. So that's correct.

Therefore, the correct answer should be d) 210.

{"correct_answer_key":"d"}

กรกชมีเงิน 85 บาท และให้ขจรไป 15 บาท ทำให้กรกชมีเงินเหลือ 85 - 15 = 70 บาท. ตามโจทย์ กรกชมีเงินเป็น 1/3 ของขจร ดังนั้น ขจรมีเงิน 70 * 3 = 210 บาท.

เดิมขจรมีเงินน้อยกว่าคิมหันต์ 100 บาท ดังนั้นคิมหันต์มีเงิน 210 + 100 = 310 บาท.

กรกชมีเงิน 85 บาท และคิมหันต์มีเงิน 310 บาท ดังนั้น กรกชมีเงินน้อยกว่าคิมหันต์ 310 - 85 = 225 บาท.

แต่ไม่มีตัวเลือกที่ตรงกับคำตอบนี้ ดังนั้นเราจะต้องตรวจสอบการคำนวณอีกครั้ง.

{"correct_answer_key":"c"}

Alright! Let's tackle this problem step by step. First, I need to understand what's being asked. The question involves three people: กรกช, ขจร, and คิมหันต์.

We know that กรกช has 85 baht initially. He gives 15 baht to ขจร. After giving away 15 baht, กรกช has 70 baht left. According to the problem, after this transaction, กรกช's money is 1/3 of ขจร's money. So, if กรกช has 70 baht, which is 1/3 of ขจร's money, we can calculate ขจร's total money by multiplying 70 by 3, which gives 210 baht. However, we need to remember that ขจร received 15 baht from กรกช, so originally, ขจร had 210 - 15 = 195 baht.

Next, the problem states that originally, ขจร had 100 baht less than คิมหันต์. So, if ขจร had 195 baht, คิมหันต์ must have had 195 + 100 = 295 baht.

Now, the question asks how much less money กรกช originally had compared to คิมหันต์. กรกช started with 85 baht, and คิมหันต์ had 295 baht. The difference is 295 - 85 = 210 baht.

Looking at the options provided, option d is 210, which matches our calculation.
