A sports-goods shop has tennis balls of 3 colors - red, green and white. The number of white balls is 60% more than number of red balls and the number of green balls is 12.5% less than the number of white balls. If total number of balls is 120, then how many green balls are there?

A sports-goods shop has tennis balls of 3 colors - red, green and white. The number of white balls is 60% more than number of red balls and the number of green balls is 12.5% less than the number of white balls. If total number of balls is 120, then how many green balls are there? Correct Answer 42

Given:

Total number of balls = 120

Concept used:

Ratio and proportion

Calculation:

According to the question,

5 white balls = 8 red balls

7 white balls = 8 green balls

Ratio of red, green, and white balls = 5 : 7 : 8

So, green balls = 120 × 7/20

⇒ 42

∴ 42 green balls are there

Ashutosh has a box containing 8 identical red balls, 9 identical blue balls and 10 identical green balls. He is required to distribute all these balls into three bags A, B and C such that the total number of balls in bag A is more than that in bag B, which, in turn, is more than that in bag C. Moreover, he needs to ensure that the number or red balls in bag A is more than that in bag B which in turn is more than that in bag C, and similarly for the blue and green balls. In how many ways can he do this? Each bag must contain at least one ball of each type.
