Answer» Correct Answer - Option 2 : 49

Given:

Average age of 11 cricket players = 25

The average age of 11 cricket players after coach’s age is included = 27

Concept used:

Average = (Total sum)/(Total numbers)

Calculations:

Let the age of coach be T

Initially, the average age = 25 years

Number of players = 11

Total of age for 11 players = 25 × 11 = 275 years

According to the question,

After adding the age of the coach, new average is obtained as:

⇒ (275 + T)/12 = 27

⇒ 275 + T = 27 × 12

⇒ 275 + T = 324

⇒ T = 324 – 275 = 49 years

∴ The age of the coach is 49 years
