Problem Analysis

We have a balancing scale with one side containing 1 watermelon and 6 apples, and the other side containing a weight of 2 kg, 2 watermelons, and 2 apples. The other side of the scale contains a weight of 3 kg, 1 watermelon, and 3 apples. We need to determine the mass of one watermelon and one apple.

Solution

Let's assume the mass of one watermelon is W kg and the mass of one apple is A kg.

From the given information, we can set up the following equations:

Equation 1: 1 watermelon + 6 apples = 2 kg + 2 watermelons + 2 apples Equation 2: 2 kg + 1 watermelon + 3 apples = 3 kg + 1 watermelon + 3 apples

Simplifying Equation 1: 1W + 6A = 2 + 2W + 2A -1W + 4A = 2

Simplifying Equation 2: 2 + 1W + 3A = 3 + 1W + 3A 1W = 1

From Equation 2, we can conclude that the mass of one watermelon is 1 kg.

Substituting the value of W into Equation 1: -1(1) + 4A = 2 4A = 3 A = 3/4 = 0.75

Therefore, the mass of one watermelon is 1 kg and the mass of one apple is 0.75 kg.

Answer

The mass of one watermelon is 1 kg and the mass of one apple is 0.75 kg.
