Therefore the number is increased by 10.

Step-by-step explanation:

Let the number be x.

First the number is increased by 30.

Then the number becomes = x+30

Then the number is decreased by 20.

The new number is = (x+30-20)

                                =(x+10)    [ like terms are added]

The difference between new number and original number is

=(x+10-x)

=10

Therefore the number is increased by 10.
