The average age of A and B is 40 years. If C were to replace A, the average would be 38 and if C were to replace B, the average would be 52. What are the age of A, B and C?	Choose the most appropriate option:  A) 40, 38, 52  B) 40, 20, 26  C) 36, 80, 20  D) 54, 26, 50  E) None of the above
Given A + B = 80â€¦(i)   C + B = 76 â€¦ (ii)   A + C = 104â€¦(iii)   (i) + (ii) + (iii) â‡’ A + B + C = 130 â€¦(iv)   from (i) and (iv), we get   C = 50 years   âˆ´ B = 26 years and A = 54 years   Answer 54, 26, 50
