Answer:
10 liters of the paint will be used to paint the house.
Step-by-step 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
[tex]\frac{15}{x}= \frac{60}{40}[/tex]
x = [tex]\frac{40\times 15}{60}[/tex]
= 10 liters
Therefore, 10 liters of thinner will be used to paint the house.
