Correct Answer - Option 2 : 70 runs
Given:
13th innings he scores (x) = 130 runs
Increase in average = 5 runs
Innings = 13
Formula used:
Average after n innings = x – y(n - 1)
Calculations:
Average after n innings = x – y(n - 1)
Required Average = 130 – 5(13 - 1)
⇒ 130 – 60
⇒ 70 runs
∴ His new average is 70 runs.
