Example 1:

If we want to increase 40 by 20%

Solution:

The 20% of 40 is:

= 20/100 x 40

= 8

Add the 20% i.e., 8 to 40

= 8+40

= 48

You can apply another formula.

Example 2:

40+20% =?

Solution:

=  (100+20)% x 40

= 120/100 x 40

= 12 x 4

= 48

Example 3:

Increase 60 by 30%

Solution:

=  30/100 x 60

=  18

= 18 + 60

= 78

Example 3:

If you want to increase 80 by 40%

= (100+40)% x 80

= 140/100 x 80

If we want to decrease 50 by 20%, then:

Solution:

= 20/100 x 50

= 10

Subtract it from the given value:

= 50-10

= 40

We can also apply the same formula we applied in the increase equation.

Example 2:

If we want to decrease 20% from 50

Solution:

= (100-20)% x 50   (apply formula)

= 80/100×50

= 8 x 5

= 40

Example 3:

If we want to decrease 30% from 90.

Solution:

= 30/100×90 (cross multiplication)

= 27

= 90-27

= 63
