Question

My income was increased bt 10% and later decreased by 10%. What is the total change in percent in my income?

Answer 1

1st income is 100%
Then increased by 10% so became 110%
Then decreased by 10% so (110-11)% = 99%
Therefore, your final profit income will be - 1%

Answer 2

Let your original salary be Rs.100
After 10% increment , salary : 100+10 : Rs 110
Now , a decrement of 10% on Rs 110 : Rs 99
So , %age change : (100-1)/ 100 * 100 = 1% decrease
