A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Find his average after 17th inning.
1. 30
2. 37
3. 39
4. 40

Answer 1

Correct Answer - Option 3 : 39

GIVEN:

Batsman score in 17th inning = 87 and his average increases by 3 

CALCULATION:

Batsman score in 17th inning = 87 and his average increases by 3 

⇒ Let the average after 17th inning = x

⇒ Average after 16th inning = (x - 3)

⇒ 16 × (x - 3) + 87 = 17x

⇒ x = 87 - 48 

⇒ x = 39

∴ His Average after the 17th inning will be 39
