Question

21. In a cricket match the average runs made by 11 players were calculated as 40. Later on it was
discovered that the score of a player who had actually made 11 runs was read as 22. Find the
correct average.
[Ans: 39 runs]​

Answer 1

Answer:

39

Explanation:

sum of observations=x

no. of observations =11

wrong average=x/11

=40

sum=40*11

440

now, score was 11 instead of 22

this affected the average as there was an increase of 11 runs in the sum (22-11)

therefore, we will minus the excess runs

correct average = 440-11/ 11

=329/11

=39 runs

Answer 2

Answer:

as mentioned above, that's the correct answer
