In a 64 liter of mixture of milk and water, the quantity of water is 20 liter and the rest is milk. 1/4th of the mixture is taken out. How much milk should be added in the mixture so that the quantity of milk would be 3 times the quantity of water? Correct Answer 12 liter

1/ 4th of the mixture is taken out

Means quantity of milk has taken out 

⇒ 1/ 4th of 44 = 11 liter

And the quantity of water has taken out

⇒ 1/ 4th of 20 = 5 liter

Remaining Quantities of milk and water is 33 liter of milk and 15 liters of water

Now we have to make it in the ratio of 3 : 1 by adding milk

⇒ (33 + x)/ 15 = 3/1

⇒ x = 12 liter
