Question

By increasing 100 to 25% How much percent should be decreased to get the se number​

Answer 1

Answer: 20%

Step-by-step explanation:

100 + (100 x 25/100) = 25, you are increasing so you add the original number to the percentage, getting 125

you need to get back to the original number, therefore,

125 - (125 * x/100) = 100

125 - 125x/100 = 100

-125x/100 = -25

-125x = -2500

x = 20%
