Answer 1

Step-by-step explanation:

Let the required number be 100.

Then, according to the question.

= Firstly the number is increased by 10%

= 100+(100*10)/100

= 100+10

=110

Secondly it is decreased by 10%

= 110-(110*10)/100

= 110-11

= 99

Net increase or decrease percantage

= (Original price-New number)*100/100

= (100-99)*100/100

= (1*100)/100

= 100/100

= 1%

So,net decrease is 1%.
