A Jar contains a mixture of AB in the ratio 3:2. 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) 18 B) 15 C) 16 D) 20 E) 25
10 litres of mixture that is replaced will contain 6 litres of 18 and 4 litres of B (as 18:B = 3:2)   Let the initial volume of the mixture be 3K + 2K = 5K   So by condition ,   [ 3K-6 ]/ [ 2K-4+10 ]   3  + 2=

5K   So by condition ,   [ 3K-6 ]/ [ 2K-4+10 ]= 2/3 9k-18 =4k-8+20 5 k= 12+18 k = 6   Solve for K which is K = 6   So initial volume of liquid 18 = 3K = 18 litres   18nswer : 18
