Answer:
Correct Answer :9% decrease
Explanation:
Let a original number is = 100
New number, increased by 30% = 100 + (30% of 100) = 130 Now it is reduced by 30% = 130 - (30% of 130) = 91
that means, in net it is 100-91 = 9% decreasing
Or
If something increased by x% and reduced by x% then net effect will be loss of (x/10)² %
= (30/10)²
