Question

В двух мотках было одинаковое количество провода. Когда от первого мотка отрезали 36 метров, а от второго - 16, то в первом мотке осталось провода в 2 раза меньше, чем во втором. Сколько метров провода было в каждом мотке сначала?

Answer 1

36-16=20 чота не датукиваю

 

Answer 2

Problem Analysis

We are given that there were two coils of wire with the same amount of wire initially. When 36 meters were cut from the first coil and 16 meters were cut from the second coil, the amount of wire remaining in the first coil was half of the amount remaining in the second coil. We need to find the initial amount of wire in each coil.

Solution

Let's assume the initial amount of wire in each coil is x meters.

According to the given information, when 36 meters were cut from the first coil and 16 meters were cut from the second coil, the amount of wire remaining in the first coil was half of the amount remaining in the second coil.

So, the equation can be formed as follows:

x - 36 = (x - 16) / 2

To solve this equation, we can simplify it:

2(x - 36) = x - 16

Simplifying further:

2x - 72 = x - 16

x = 56

Therefore, the initial amount of wire in each coil was 56 meters.

Answer

The initial amount of wire in each coil was 56 meters.
