Answer 2

Problem Analysis

We are given two boxes of candies, and the total weight of the candies in both boxes is 90 kg. When 25% of the candies from the first box are transferred to the second box, the number of candies becomes equal in both boxes. We need to determine the initial weight of candies in each box.

Solution

Let's assume the initial weight of candies in the first box is x kg. Since 25% of the candies from the first box are transferred to the second box, the weight of candies in the first box becomes 0.75x kg. The weight of candies in the second box is initially 90 - x kg.

According to the problem, when 25% of the candies from the first box are transferred to the second box, the weight of candies becomes equal in both boxes. Therefore, we can set up the following equation:

0.75x = 90 - x

Solving this equation will give us the value of x, which represents the initial weight of candies in the first box.
