Question :

In a cricket team, the average age of eleven players in 28 years. What is the age of the captain?

Statements :

a. The captain is eleven years older than the youngest player.

b. The average age of 10 players, other than the captain is 27.3 years.

c. Leaving aside the captain and the youngest player, the average ages of three groups of three players each are 25 years, 28 years and 30 years respectively.
A) All a,b and c follows
B) Only a and c follows
C) Either b alone or a & b follows
D) None

=> Option C is the correct answer.

Read description:

Total age of 11 players = (28 x 11) years = 308 years.
 I. C = Y + 11  =>  C - Y = 11 .... (i)
II. Total age of 10 players (excluding captain) = (27.3 x 10) years = 273 years.
•°• Age of captain = (308 - 273) years = 35 years.

Thus, C = 35. .... (ii)
From (i) and (ii), we get Y = 24

III. Total age of 9 players = [ (25 x 3) + (28 x 3) + (30 x 3)] years = 249 years.

•°• C + Y = (308 - 249) = 59 .... (iii)
From (i) and (iii), we get C = 35.

Thus, II alone gives the answer.
Also, I and III together give the answer.

•°• Correct answer is (C).
