Problem Analysis

We are given that the total mass of 20 identical boxes of candies is 500 grams less than the total mass of 25 identical boxes of candies. We need to find the mass of one such box.

Solution

Let's assume the mass of one box of candies is x grams.

According to the given information, the total mass of 20 boxes is 500 grams less than the total mass of 25 boxes. Mathematically, we can express this as:

20x = 25x - 500

To find the value of x, we can solve this equation.

20x - 25x = -500

-5x = -500

Dividing both sides of the equation by -5:

x = 100

Therefore, the mass of one box of candies is 100 grams.

Answer

The mass of one box of candies is 100 grams.
