Final price of the ream of the paper = rs. 150

To find,

The amount of percentage increase.

Solution,

First of all,we need to calculate the amount of increase in the normal numerical value of the price of the ream of the paper.

Increase amount = Final price - Initial price = 150 - 120 = rs. 30

Now,we have to calculate the percentage of increase by using the following mathematical formula,

= 100 × Increase amount/Initial price

= 100 × 30/120

= 100/4

= 25%

Hence,the price increased for the percentage of 25%.

Step-by-step explanation:

Increase amount= final price - Initial price

=150-120=30rs

100*increase amount/initial price= 100*30/120=100/4=25%
