Correct Answer - Option 2 : 41

Given:

The score of 12th innings = 63 

The average increase = 2

Formula used:

Total score = average score × number of innings

Calculation:

Let the average score be x

⇒ Total score = 12x      ----(1)

According to the question

⇒ The average of 11 innings = (x - 2)

⇒ Total score = (x - 2) × 11 + 63      ----(2)

On comparing eq (1) and eq (2), we get

 (x - 2) × 11 + 63 = 12x

⇒ x = 63 - 22 = 41

∴ The average of his score after 12th innings is 41.
