The average of 10 numbers is calculated as 15. It is discovered later on that while calculating the average, one number namely 36 was wrongly read as 26. The correct average is?
The average is 15.
so, the total of the numbers is 15 x 10 = 150.
Now, the question says mistakenly 36 is written as 26. This means, to the total, there is 10 added. (36-26 = 10).
New total is 150+10 = 160.
New average = 160/10 = 16.
The average is 15.
so, the total of the numbers is 15 x 10 = 150.
Now, the question says mistakenly 36 is written as 26. This means, to the total, there is 10 added. (36-26 = 10).
New total is 150+10 = 160.
New average = 160/10 = 16.
