The average age of A and B is 50 years. If C were to replace A, the average would be 50 and if C were to replace B, the average would be 40. What are the age of A, B and C?	Choices:
A) 100,100, 80 B) 50, 50, 40 C) 40, 60, 40 D) 50, 60, 40 E) None of the above
Given A + B = 100â€¦(i)   40, 60, 40 + B = 100â€¦ (ii)   A + 40, 60, 40 = 80â€¦(iii)   (i) + (ii) + (iii) â‡’ A + B + 40, 60, 40 = 140â€¦(iv)   from (i) and (iv), we get   40, 60, 40 = 40years   âˆ´ B = 60 years and A = 40 years   Answer 40, 60, 40
