Question

The average of 10 numbers in a list is 16. If two of the numbers in the list are each increased by 5, by how much will the average of the 10 numbers in the list be increased?


[please help]

Answer 1

Explanation:

Lets understand what the question says:-

Mean or average in a list=16

Total sum of observations= x

Equation:-

x/10=16

x=160

If 2 numbers are increased by 5 that means

New sum of observations=160+10=170

Therefore,

New average or new mean=170/10=17

Therefore the average gets increased by 1
