Question

There are two vessels A and B containing 25 litres each of pure milk and pure water respectively. 5 litres of milk from A is taken and poured into B, then 6 litres of mixture from B is taken and poured in A. What is the ratio of water from vessel A and B:

Answer 1

Water : Milk = 5:21 in A and 5:1 in B
.
Start : 25 L milk in A and 25 L water in B
5 L A => B : Containers now contain 20 L milk in A and 25 L water + 5 L milk in B
6 L B contains 5 L water + 1 L milk
6 L B => A : Containers now contain 21 L milk + 5 L water in A and 20 L water + 4 L milk in B
Ratio water : milk = 5 : 21 in A and 20 : 4 in B
