Question

The average age of a cricket team playing a test match is 30. The average age of a group of five of
the players is 25, and that of another group of five players who are different from the first five, is 30.
What is the age of the captain who was not included in either of these two groups?

Answer 1

Answer:

ans is 55

Step-by-step explanation:

average=total age of all 11 members/total no. of members

let x be age of captain

then total age of first group=25x5= 125

for second group= 30x5=150

then,30=(x+125+150)/11

solving we get x=55

Hence age of captain=55 years
