The average of runs scored by Afridi of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4 ?

OPtion

1) 71
2) 69
3) 73
4) 67
5) 75
6) 76
7) 66
8) 65
9) 64
10) None of these

Solution

Average = total runs / no.of innings = 32

So, total = Average x no.of innings = 32 x 10 = 320.



Now increase in avg = 4runs. So, new avg = 32+4 = 36runs

Total runs = new avg x new no. of innings = 36 x 11 = 396

Runs made in the 11th inning = 396 - 320 = 76
