The average age of eleven cricket players is 20 years. If the age of the coach is also included, the average age increases by 10%. The age of the coach is
-
- 48 years
- 44 years
- 40 years
- 36 years
- 48 years
Correct Option: B
Here , The average age of eleven cricket players = 20 years
Total age of 11 players = 11 × 20 = 220 years
If the age of the coach is also included, the average age increases by 10%
i.e. Total increase average = 20 of 10% = 2
New average of 11 players and the coach = 20 + 2 = 22 years
Total age of 11 players and the coach = 12 × 22 = 264 years
∴ Age of the coach = (264 – 220) years = 44 years
