Question

a number is increased by 20% and then the increased number is decreased by 20% find the net increase or decrease per cent​

Answer 1

Answer:

4%

Step-by-step explanation:

Let the number be =100

Increase in the number =20% of 100

= 100\20 ×100

=20

Increased number =100+20

=120

The resulting number decreased by 20%

Decrease in the number =120\20 ×120

=24

New number =120−24

=96

Now, net decrease =100−96

Net % decrease = Original number\Net decrease ×100

= 100\4×100

=4%

Hence the net percent decrease is 4%.
