47 years

Step-by-step explanation:

average age of 11 players and the coach is 18 yr.

(sum of ages of 11 members + age of coach)/13 =18

(sum of ages of 11 members + age of coach)= 18 X 13

=234 ----------->i

average age of 11players = 18-1

sum of ages of 11 members /11= 17

I - ii

age of coach = 234 - 187

= 47 years
