Quantitative Aptitude ( CCS) Problems based on Ages

Four years ago, the ratio of the ages of A and B was 5 : 9. 8 years hence the ratio will be 2 : 3 respectively. Find the present age of B?

Let 4 years ago A’s age = 5x, B’s age = 9x
Then 4+8 = 12 years after – (5x+12)/(9x+12) = 2/3
Solve, x = 4
B’s present age = 9x+4 = 40
