A number is first decreased by 5% and then increased by 5%. What will be the net increase or decrease?

Correct option is A

Given:

A number is first decreased by 5% and then increased by 5%.
Formula Used:
When a value is changed successively by x% and then y%, the net change (%) is:

Net Change = $$x + y + \frac{xy}{100}$$​

Solution:

Net Change =$$-5 + 5 + \frac{(-5)(5)}{100}$$​

Net Change = $$0 - \frac{25}{100} = -0.25\%$$​

Net decrease of 0.25%.
