Question

A number is increased by 10% and the resulting number is increased by 20% what is the oval percent increase in the number

Answer 1

Let the no. Be 100
So 100+10/100*100=110
Tg3n 110+20/100*110=110+22=132
So overall increase percent =
(132-100)/100=32/100*100=32%

Answer 2

let original number: 100x

10% increase: 110x

20% increase on 110x: (20/100)*110x + 110x
                                       =132x 

overall percentage: (132x-100x)/100x *100%
                                 = 32x / 100x     * 100%
                                 = 32%
