The correct answer is
Given: Age of Captain = 31
Relation between age of Captain and Keeper.
To Find: Average age of team.
Solution:
Age of Keeper = Age of Captain + 4
= 31 + 4
Age of Keeper = 35
Average age of team =
Average age of team after excluding Captain and Keeper =
Now, according to the condition "the ages of these two are excluded, the average age of the remaining players is two year less than the average age of the whole team".
Average age of remaining players = Average of whole team - 2
= - 2
=
12(sum of ages of 10 players) = 10(sum of ages of 10 players) + 420
2(sum of ages of 10 players) = 420
sum of ages of 10 players = 210
So, now put the value of this in formula of average age of whole team written above.
Average age =
= 23
Hence, the average age of whole team is 23.
