Answer 1

Answer:

Amitabh = 49 years

Step-by-step explanation

Let A, B, C be the age of Amitabh, Bachan and Chandan respectively.

Average Age of A, B, C = 45

Total Age A + B + C = 45*3 = 135.....(1)

Average age of A and B = 40

A + B = 40*2 = 80........(2)

Average age of B and C = 43

B + C = 86.......(3)

Subtract (3) from (1)

A + B + C - B - C = 135 - 86

A = 49 years
