Question

A Batsman scored 15 runs in an over. He scored average ___ runs on each man. Answer Is 2.5. Explain​

Answer 1

Let the average of runs for 16 innings be A.

Then, average of runs for 17 innings = A + 3

Total runs for 16 innings = 16 A

⇒ Total runs for 17 innings = 16 A + 85

Given,  

17

16A+85

​

=A+3

⇒16A+85=17A+51⇒A=34

∴ Average of 17 innings = 34 + 3 = 37
