@jashholmes said:A cricketer had played a certain number of innings during the year. He finds that if he had not played the last game when he made 20 runs, or if he had played an extra innings and made 56 runs, he would have increased his average by 1. What was his average?
let x1+x2+...xn/n=A,
(x1+x2+...xn)-20/n-1=A+1,
so An-20=(A+1)(n-1)
similarly An+56=(A+1)(n+1)
solving A=37......sahi hai kya?

cost*consumption = expenditure
so x*y = e---------> x = e/y
x1*88.89/100*y = 133/100*e--------> 133/88.89y*e
% change = (133/88.89y*e - e/y)/e/y*100 = 133 - 88.89/88.89*100 = 49.6% = 50% ?
@maroof10 said:@audiq7 explain plz
