Question 55

In Jar A, 140 litre milk was mixed with 40 litre water. Some of this mixture was taken out from Jar A and put in Jar B. If before the operation, there was 17 litres of milk in Jar B, and afterwards the resultant ratio between milk and water in jar B was 19 : 3 respectively, what was the amount of mixture that was taken out from Jar A ? ( in litre)

Solution

Milk to water ratio in Jar A is 140:40 = 7:2. Let the quantity of taken out mixture from jar A = 9x litre.

Hence, milk will be 7x and water will be 2x litres.

Therefore, (7x + 17) / 2x = 19/3

=>x = 3

Hence, amount taken out is 9*3 = 27 litres.
