Question

You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 1 parts cream and 3 part blue. How much blue paint will you need to mix with 4 litres of red?. Single line text.

Answer 1

6 litres of blue color should be mixed.

Explanation:

To get the paint color as per my wish, paint of different colors are mixed in the ratio = Red : Cream : Blue

= 2 : 1 : 3

In this mixture, ratio of red and blue color = 3 : 2

This ratio will be constant for any amount of mixture.

Therefore,
`\frac{\text{Amount of Blue color}}{\text{Amount of red color}}=(3)/(2)`

`(b)/(4)=(3)/(2)`

b =
`(3)/(2)* 4`

b = 6 litres

Therefore, 6 litres of blue color should be mixed with the 4 litres of red color.
