Question

A batsman in his 13th innings makes a score of 77 and there by increases his average by 4. what is his average after the 13th innings? ( A ) 28 ( B ) 30 ( C ) 29 ( D ) 27

Answer 1

Answer:

C) 29

Step-by-step explanation:

Let the average of batsmen after 12 innings be x.

So total runs scored after 12 innings = 12x.

Given,

He scored 77 in 13th inning and average increased by 4.

=> 12x + 77 = 13(x + 4)

=> 12x + 77 = 13x  + 52

=> x = 77 - 52 = 25

So his average after 12 innings was 25.

Thus his average after 13 innings = 25 + 4 = 29.
