Answer» Correct Answer - Option 2 : 12

Given:

Average age of the first three man = 8

Average age of the last three man = 16

Average age of the 5 men = 12

Formula used:

Sum of ages = Average × Number of persons

Calculation:

Total age of 5 men = 12 × 5 years

⇒ 60 years

Total age of first three-man = 8 × 3

⇒ 24 years

Total age of last three men = 16 × 3

Age of third man is = (24 + 48) – 60 years

⇒ 72 – 60 years

⇒ 12 years

The age of third man is 12 years
