Question

A is three times as old as B. C was twice-as old as A four years ago. In four years&#39; time, A will be 31. What are the present ages of B and C ?-A-9, 46B-9, 50C-10, 46D-10, 50-B-9, 50

APTITUDE CRACK · Accepted Answer

B 9, 50 Explanation: We have : A = 3B ...(i) and C 4 = 2 (A 4) ...(ii) Also, A + 4 = 31 or A= 31 4 = 27. Putting A = 27 in (i), we get: B = 9. Putting A = 27 in (ii), we get C = 50.

Arithmetic Reasoning
