Madhya Pradesh Police Exam Model Paper 2

Given:
In a cricket team, the average age of 11 players is 22
years. When the age of team coach is included to it, the average age increases by 1.
Formula Used:
average = sum of observations/number of observations
Calculation:
⇒ Average age of 11 players = 22 years
⇒ Total age of 11 players $=22\times 11=242$ years
Let age of coach = x years
According to ques,
$\Rightarrow 242+\mathit{x}/12=23$ $\Rightarrow 242+\mathit{x}=23\times 12=276$ $\Rightarrow \mathit{x}=276-242=34$ years
