In a mixture of 60 liters, the ratio of milk and water 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is:
The correct option is A
Quantity of milk =60×23=40 liters Quantity of water in it = ( 60 - 40) liters = 20 liters. New ratio = 1 : 2 Let quantity of water to be added further be x liters. Then, milk: water =4020+x Now, 4020+x=12 ⇒x=60 So, quantity of water to be added = 60 liters.
