The average age of A and B is 30 years. that of B and C is 32 years and that of C and A is 34 years.
Concept used:
Average
Calculation:
The average of A and B is 30 years
⇒ (a + b) / 2 = 30
⇒ (a + b) : 30 × 2 = 60
The average of B and C is 32 years
⇒ (b + c) / 2 = 32
⇒ (b + c) = 32 × 2 = 64
The average of A and C is 34 years
⇒ (a + c) / 2 = 34
⇒ (a + c) = 34 × 2 = 68
Average : (60 + 64 + 68)/2 = 96 years
(a + b + c) = 96
Age of c = 96 - (a + b)
Age of c = 96 - 60
Age of c = 36 years.
The answer is 36 years.
