Question

a number is increased by 10% and then decreased by 10%. find the net increase or decrease percent

Answer 1

Let the number be 100
Increase %=10%
Increase=10/100×100
=10
New number=100+10
110
Decrease%=10%
Decrease=10/100×110
=11
New number=110-11
=99
Since Original number > New Number
Therefore Decrease
Decrease=100-99
=1
Decrease%=1/100×100
=1%
