Most Upvoted Answer
15 years from now A will be thrice as old as B was 5 years ago. C is 2...
A + B + C = 3 × 20 = 60

C : (A + B) = 1 : 5
So, C = 10 and A + B = 50
A + 15 = 3(B – 5)
3B = A + 30
and A + B = 50
Solving we get B = 20 and A = 30
When C was born age of A was = 30 – 10 = 20 years
Hence, option A is correct.
