The captain of a cricket team of 11 members is 26 years old and the wicket keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team?

(a) 23 years (b) 24 years (c) 25 years (d) None of these

• ans is a)23 years
  captain age is 26years
  wk age is 29years
  the avg years of 11 players is x.-->its sum is 11x
  then avg years of 9 players is x-1.-->its sum is 9(x-1)
  if including captain and wicket keeper we get 11x
  thats is 9(x-1)+26+29=11x
  9x-9+55=11x
  2x=46
  x=23
  that is the avg age of them is 23years.

• given: (26+29+x)/11 = y
  and x/9 = y-1
  where 'x' is the sum of the ages of other team members and'y' is the average age of the team
  we can simplify this as 11y=55+x and x=9y-9
  after rearranging,it will be
  x-11y=-55 and x-9y=-9
  by solving, we get y=23
  Ans:23 years

• Ans : a) 23 years
  Caption's age =26 and wicket keeper 's age is 29
  Let x be sum of ages of team excluding captain and Wicket Keeper
  Given
  x/9= (x+26+29)/11 -1
  on solving the above we get x =198
  Avg of team = (x+26+29)/11 =253/11 =23
  Ans : 23 years

• ANS: 23years
  using given data
  (9x/9)+1 = (9x+55)/11......(1)
  solve this we get ANS: 23years
  where "x" is avg age of remaining 9 players
  and age of captain and wicket keeper is 55.
