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. **
