Answer:

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.
