Question

В первом ящике было в 4 раза больше яблок, чем во втором ящике. В двух ящиках вместе - 100 кг яблок. Сколько кг яблок в первом ящике ?

Answer 1

х кг - во втором ящ.

4хкг. - в первом ящ.

4х+х=100кг.

5х=100кг.

х=100:5

х=20кг. было во втором ящ.

20 * 4 = 80кг в первом ящ.

Answer 2

Пусть кол-во кг  во 2 ящике равно х, тогда в 1 ящике-4х

1) х+4х=100

5х=100

х=20 кг во 2 ящике

2) 4х=4*20=80 кг

Ответ: 80 кг яблок в 1 ящике.

Answer 3

Problem Analysis

We are given two boxes of apples, and the weight of the apples in both boxes combined is 100 kg. The first box contains four times as many apples as the second box. We need to determine the weight of the apples in the first box.

Solution

Let's assume the weight of the apples in the second box is x kg. According to the problem, the first box contains four times as many apples as the second box. Therefore, the weight of the apples in the first box is 4x kg.

The total weight of the apples in both boxes is 100 kg. So we can write the equation:

x + 4x = 100

Simplifying the equation:

5x = 100

Dividing both sides of the equation by 5:

x = 20

Therefore, the weight of the apples in the second box is 20 kg. Since the first box contains four times as many apples as the second box, the weight of the apples in the first box is:

4 * 20 = 80 kg.

The weight of the apples in the first box is 80 kg.

Answer

The weight of the apples in the first box is 80 kg.
