Answer:

10 liters of the paint will be used to paint the house.

Explanation:

A painter uses the paint and thinner in the ratio of 60 : 40.

He uses 15 liters of paint to paint a house.

Let he uses x liters of the thinner with the paint.

Then the ratio of paint and thinner will be 15 : x

Since 15 : x is same as 60 : 40 then


(15)/(x)= (60)/(40)

x =
(40* 15)/(60)

= 10 liters

Therefore, 10 liters of thinner will be used to paint the house.
