Answer:
Step-by-step explanation:
Let the number x is equal to = 100
1: Increase the number by 25%
100 + 25% = 125
2: Decrease the number by 25%
125 - 25% = 93.75
3: Now we will calculate, what percentage of 93.75 to 100. To get our answer:
Obtain number: 93.75
Total number: 100
Obtain ÷ total * 100
93.75 ÷ 100 * 100 = 93.75%
Now the number has decreased from 100% to 93.75%, we have to calculate how much net % is decreased. For that,
93.75 % - 100% = - 6.25%
The net decrease will be -6.25%.
