Answer:
Step-by-step explanation:
Let the required number be 100%.
According to the question,
⇒ First, the number is increased by 10%
⇒ 100 + 10
= 110%
Secondly, it is decreased by 10%
⇒ 110 - (110*10)/100
⇒ 110 - 11
⇒ 99%
Net increase or decrease percentage
= (Original Number - New Number)
= 110 - 99
= 1%
So, net decrease is 1%
