Best answer
Correct Answer - Option 2 : 42

Given:

Number of innings = 16

 Score in 16th inning = 12

Average decreased by = 2 runs

Concept:

Average value = Sum of all values/Number of values

Calculation:

Let, his new average = x

According to the question,

⇒ 15 × (x + 2) + 12 = 16x

⇒ 15x + 30 + 12 = 16x

⇒ x = 42

∴ His new average = 42
