A) 60 years

B) 37 years

C) 62 years

D) 15 years

Four years ago, average age of A,B,C 

[(A-4) + (B-4) + (C-4)]/3 =25

               A + B + C  -12 = 75

                      A + B + C = 87 ….(I) 

Five yeas ago, average of B and C 

          [(B-5) + (C – 5)]/2 = 20

                    B + C – 10 = 40 

                         B + C = 50 ……(ii) 

Solving (i) and (ii) 

                                A =37 years
