Best answer
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.
