A number is first increased by 16% and then increased by 14%. The number, so obtained,
is now decreased by 30%. What is the net increase or decrease percent in the original number

let the no. 100

after 16% increase it becomes 116

after 14%increase 116 + 116*14%
=132.24

after 30% decrease. =132.24 - 132.24*30%
= 92.57

decease in original no. = 100 - 92.57
= 8.43

First 16+14+16x14/100=132.24
Now 132.24*30%=92.57
100-92.57=8.43
