ANSWER

The answer is 3 grams

GIVEN

Mass of the plastic cup = 2.5 grams

TO FIND

Mass of one ball.

SOLUTION

We can simply solve the above problem as follows;

Given,

Mass of plastic cup = 2.5 grams

Value on weighing scale = 32.5 grams

Number of balls in the cup = 10

Let the Weight of 1 ball = x grams

10x + 2.5 = 32.5

10x = 32.5-2.5

10x = 30

x = 30/10 = 3 grams

Hence, The answer is 3 grams
