The sum of the present ages of A and B is 50. After 2 years B’s age will be 2 more than C’s age then. If A is younger than C by 4 years, find the age of B 8 years ago. 

The difference between B and C’s age will remain same
Let C’s present age = x, so B’s present age = (x+2)
sum of the present ages of A and B is 50, so A’s age becomes = 50-(x+2) =48-x
now A is younger than C by 4 years, so 48-x = x – 4
Solve, x = 26
B’s present age = x+2 = 28
Before 8 years, B’s age = 28-8 = 20
