Answer 2

Problem Analysis

We are given three boxes of apples. The weight of the apples in the first box is 12 kg. The weight of the apples in the second box is three times less than the first box, and the weight of the apples in the third box is 4 kg more than the first box. We need to find the number of apples in each box.

Solution

Let's assume the number of apples in the first box is x.

According to the problem, the weight of the apples in the second box is three times less than the first box. This means the weight of the apples in the second box is (1/3)x.

The weight of the apples in the third box is 4 kg more than the first box. This means the weight of the apples in the third box is x + 4.

To find the total number of apples, we need to add the number of apples in each box.

So the total number of apples is x + (1/3)x + (x + 4).

Simplifying the expression, we get:

x + (1/3)x + (x + 4) = 12

Now, let's solve this equation to find the value of x.

Solving the Equation

To solve the equation, we can combine like terms and isolate x.

x + (1/3)x + (x + 4) = 12

Combining like terms:

(4/3)x + (x + 4) = 12

Multiplying through by 3 to eliminate the fraction:

4x + 3(x + 4) = 36

Expanding the brackets:

4x + 3x + 12 = 36

Combining like terms:

7x + 12 = 36

Subtracting 12 from both sides:

7x = 24

Dividing both sides by 7:

x = 24/7

So the number of apples in the first box is 24/7.

To find the number of apples in the second box, we substitute the value of x into the expression (1/3)x:

(1/3)(24/7) = 8/7

So the number of apples in the second box is 8/7.

To find the number of apples in the third box, we substitute the value of x into the expression x + 4:

(24/7) + 4 = (24 + 28)/7 = 52/7

So the number of apples in the third box is 52/7.

Answer

Therefore, the number of apples in the three boxes is as follows: - First box: 24/7 - Second box: 8/7 - Third box: 52/7

Please note that the number of apples in each box is a fraction.
