YadeeshKumar  (13 years ago)

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.

Sivabharathi  (13 years ago)

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
