Question

To make green paint, a painter mixes yellow paint and blue paint in the ratio of 3 :2. If he
used twelve liters of yellow paint, how much blue paint did he use?
​

Answer 1

The ratio given is 3:2

So,

Let the amount of yellow paint be 3x

and the amount of blue paint be 2x

Given : amount of yellow paint used = 12 litres

therefore,

3x = 12 litres

x = 4 litres

Hence amount of blue paint used = 2x = 2×4 = 8 litres

Answer : 8 litres
