Question

a number increased by 10% and increased number is decreased by 10% show that the net decrease is 1%​

Answer 1

Let the no be 100

(100 X 10)/100 =10

Since the 10%of 100=10

new no. =100+10=110

now 10% of new no.

(10 X110)/100=11

now 110-11=99

original no.-new no.=>

100- 99 =1

therefore the net decrease is 1

HOPE THIS HELPS YOU.
