Question

The average of 100 numbers is ‘x’. If every number is increased by itself then the increase in the average is ___.

Answer 1

Dear Student,

◆ Answer -

The increase in the average is x.

● Explaination -

Initially sum of 100 numbers is -

S = 100x

Each number is increased by itself. So total increase is 100x.

S' = 100x + 100x

S' = 200x

So now average is -

x' = 200x/100

x' = 2x

So increase in average is 2x-x = x.

Thanks dear. Hope this helps you...
