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 4:

If you want to increase 80 by 40%

#### Solution:

= (100+40)% x 80

= 140/100 x 80

= 32

= 50-10

= 40

### 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
