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

Given ratio is 3:2
i.e., 3x litres of yellow paint is mixed with 2x litres of blue paint to make green paint.

so,given
12 litres of yellow paint is used

3x = 12

x = 12/3

x = 4


therefore, blue paint used is
2x = 2 × 4 = 8litre

Answer 2
