Answer 2

Required Answer:-

Given:

• A number is first increased by 25% and then decreased by 25%.

To find:

• The net increase or decrease percent.

Solution:

★ Let the number be 100.

★ After increasing 25%, we get,

= 100 + 25% of 100

= 100 + 25

= 125

★ After decreasing 25%, we get,

= 125 - 25% of 125

= 125 - 31.25

= 93.75

★ Hence, net decrease,

= 100 - 93.75

= 6.25

★ Decrease Percentage will be,

= 6.25/100 × 100%

= 6.25%

★ Hence, the number is decreased by 6.25%

Answer:

• Net decrease percentage is 6.25%
