Question

A number is increased by 20% and then decrease 25%. Find the net increase or decrease percent​

Answer 1

Answer:

let the number be 100

20% of 100 = 20

so the increased number = 120

25% of 120 = 30

so decreased number = 90

net decrease percent = 100 - 90/100 × 100 = 10/100 × 100 = 10%

so net decrease percent = 10%
