Let average run after 10th innings= X
so ......................................11th innings = (X-2)
So
Total runafter 11th innings - Total after 10th innings = Run in 11th innings
11×(X-2) - 10(X) =48
11X-22-10X=48
X=48+22
X=70
so average run after 11th innings was 70-2= 68
so ......................................11th innings = (X-2)
So
Total runafter 11th innings - Total after 10th innings = Run in 11th innings
11×(X-2) - 10(X) =48
11X-22-10X=48
X=48+22
X=70
so average run after 11th innings was 70-2= 68
