Question

A batsman is out for 23runs, which raises his batting average 15 to 16.How many runs would he have scored to bring his average upto 18?​

Answer 1

Answer:

39runs many runs would he have scored to bring his average upto 18.

Step-by-step explanation:

Let 'x' be number of runs scored.

'y' be matches played.

So- x/y= 15 and x= 15y>> equation 1. To raise his average to 16. he scored 23 runs.

x+23/y+1 = 16

x+23=16y+16

(x 15y)

15y+23=16y +16

y=7.

So x= 15y= 105.

Now to raise average to 18.

105+ k/7+1 = 18

105+k= 144

k= 39.

Therefore if the batsman would have made 39 runs, his average would have risen from 15 to 18.

hope it helps you...
