For easier calculation , Let's consider the original price as 100.

Therefore , it is reduced by 10% →

100 - (100× 10/100) = 100-10 = 90

The new price is 90.

By what percentage 90 must be increased to make the price back to original that is 100.

Let's consider that percentage as x.

90 + (90x/100) = 100

or, 90x/100 = 100-90

or, 90x = 10×100

or, x = 1000/90

or, x = 100/9

or, x = 11.11 %

Answer → The new price must be increased by 11.11% to restore it to original price.
