Question

Ms. Jhulan Goswami scores 102 runs in the 18th innings of her career and thus increases her average by 5. After the 18th inning, her average is:

Options

• 17

• 21

• 26

• 28

Answer 1

17

Explanation:

Let average after 17^th inning = x

According to the question,

`(17"x"+102)/18="x"+5`

⇒ 17x + 102 = 18x + 90

⇒ 12 = x

 Increased average = 12 + 5 = 17
