Problem Analysis

We are given the information that the combined weight of one watermelon and three identical cantaloupes is 10 kg. Additionally, we are told that the cantaloupe is twice as light as the watermelon. We need to determine the weight of the watermelon using an equation.

Solution

Let's assume the weight of the watermelon is W kg. According to the problem, the weight of the cantaloupe is half that of the watermelon, so the weight of one cantaloupe is W/2 kg.

The combined weight of one watermelon and three cantaloupes is given as 10 kg. We can set up the equation:

W + 3(W/2) = 10

Simplifying the equation:

W + 3W/2 = 10

Multiplying both sides of the equation by 2 to eliminate the fraction:

2W + 3W = 20

5W = 20

Dividing both sides of the equation by 5:

W = 4

Therefore, the weight of the watermelon is 4 kg.

Answer

The weight of the watermelon is 4 kg.
