A Jar contains a mixture of A & B in the ratio 4:1. When 10 L of Mixture is replaced with liquid B, ratio becomes 2:3. How many liters of liquid A was present in mixture initially.	Choose the correct choice from the following answers: A) 12 B) 15 C) 16 D) 20 E) 25
10 litres of mixture that is replaced will contain 8 litres of A and 2 litres of B (as A:B = 4:1)   Let the initial volume of the mixture be 4K + 1K = 5K   So by condition ,   [ 4K-8 ]/ [ K-2+10 ]   4  + 1=

<output>5</output>
5K   So by condition ,   [ 4K-8 ]/ [ K-2+10 ]= 2/3   Solve for K which is K = 4   So initial volume of liquid A = 4K = 16 litres   ANSWER:16
