Correct Answer - Option 3 : 41

Given:

Runs scored by batsman in 12th innings = 85 runs

Batting average increases by 4

Formula used:

Total runs scored = Average × Number of innings

Calculation:

Let average runs after 11th innings be n

Batting average after 12th innings = (n + 4)

Total run in 11 innings = 11n

According to the question

⇒ (11n + 85) = 12(n + 4)

⇒ 11n + 85 = 12n + 48

⇒ n = 37

Average after 12th innings = (n + 4)

⇒ 37 + 4 = 41

∴ The batting average after 12th innings is 41
