Correct Answer - Option 4 : 93

**Given:**

Score in tenth innings = 120 run

Increment in average score = 3 run

**Formula used:**

Average = Sum of all observation/Number of observation

**Calculation:**

Let average of 9 innings be x runs

⇒ Sum of score after ten innings = 9x + 120

According to the question,

⇒ (9x + 120)/10 = x + 3

⇒ 9x + 120 = 10x + 30

⇒ x = 90 runs

⇒ Average after tenth innings = 90 + 3 = 93 run

**∴ The average of Rohit Sharma after tenth innings is 93.**
