Question 81

Average age of a team having 12 players is 23 years. If the age of the coach is also included, then the average age increases by 2 years. What is the age (in years) of the coach?

Solution

Average age of team of 12 players = 23 years

=> Total age of the team = $$12\times23=276$$ years

Let the age of coach = $$x$$ years

Average age of team including coach = 23 + 2 = 25 years

=> $$\frac{276+x}{13}=25$$

=> $$276+x=25\times13=325$$

=> $$x=325-276=49$$ years

=> Ans - (C)
