Question

Answer 1

The number will be same which it was at first

Answer 2

Given,

A number is increased by $5$% and the increased number is decreased by $5$%.

Let,

A number be $x$

A number is increased by $5$% $= x+5$%

The increased number is decreased by $5$%$= x+5$%$-5$%

$= x$

Therefore, as there is no change in the number, the net increase or decrease percent will be zero.
