Answer 1

Answer:- 12 years 3 months

Step-by-step explanation:

Given:

The ages of A, B and C are 8 years 10 months, 15 years 6 months, 12 years 5 months respectively.

Concept Used:

Average = Sum of all observation ÷ Number of observation

1 year = 12 months

Calculation:

The age of A is 8 year 10 month = (8 × 12) + 10 = 106 months

The age of B is 15 year 6 month = (15 × 12) + 6 = 186 months

The age of C is 12 years 5 months = (12 × 12) + 5 = 149 months

Average age of A, B and C is (106 + 186 + 149)/3 = 147 months

⇒ 12 years 3 months [∵ 1 year = 12 months]

∴ The average age of A, B and C is 12 years 3 months
