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.
