Question

Я ящеке лежали яблоки. Сначала из него взяли 25% яблок, а затем 70% остатка. После чего в ящике осталось 48 кг яблок. Сколько яблок было в ящике первоначально?

Answer 1

100-25=75% яблок осталось после первого раза
75%=0,75
70%=0,7
0,75*0,7=0,525 яблок взяли второй раз
0,25+0,525=0,775яблок взяли всего
1-0,775=0,225 всех яблок осталось после второго раза
48:0,225=213 1/3кг было яблок
это ответ по твоим данным

Answer 2

Problem Analysis

To solve this problem, we need to determine the initial number of apples in the box. We are given that 25% of the apples were taken from the box, followed by 70% of the remaining apples. We also know that after these two steps, there were 48 kg of apples left in the box.

Solution

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

Step 1: 25% of the apples were taken from the box. This means that 75% of the apples remained in the box. The number of apples remaining after the first step is 0.75x.

Step 2: 70% of the remaining apples were taken from the box. This means that 30% of the apples remained in the box. The number of apples remaining after the second step is 0.3 * 0.75x.

We are given that after these two steps, there were 48 kg of apples left in the box. We can set up the following equation to solve for x:

0.3 * 0.75x = 48

Simplifying the equation:

0.225x = 48

Dividing both sides of the equation by 0.225:

x = 48 / 0.225

Evaluating the expression:

x ≈ 213.33

Therefore, there were approximately 213 apples in the box initially.

Answer

The initial number of apples in the box was approximately 213.
