Question

If two out of every three balls in a multi color package is pink how many balls in a package of 21 balls will be pink

Answer 1

14 balls will be pink out of 21 balls.

Explanation:

Given that:

2 out of every 3 balls are pink in a multi color package.

Ratio of pink balls to balls drawn = 2:3

Number of balls in package = 21 balls

Number of pink balls = x

Ratio = x:21

This is a proportional relationship

2 : 3 :: x : 21

Product of mean = Product of extreme

3x = 21*2

3x = 42

Dividing both sides by 3

`(3x)/(3)=(42)/(3)\\x=14`

Hence,

14 balls will be pink out of 21 balls.
