Answer 1

let x be the total no. of score in 10 innings.
therefore, x/10 is the average of 10 innings
average increased by 2
therefore new average is x/10+2= (x+20)/10
and total score after 11 innings are x+68
therefore (x+68)/11 = (x+20)/10
10x+680=11x+ 220
x= 460
therefore putting x value
new average is 48.
