Answer:

It can easily be understood if it is expressed as percent. We will follow the following steps to convert the increase into percent.

Step I: First find the increase in value

Step II: Divide it by the original quantity

Step III: Multiply the fraction by 100 and put percent sign (%)

Formula for finding the increase % is Increase in value/Original value × 100 %.

Note: Increase percent is calculated on the original value.

For example:

If price of milk increases from $4 per litre to $5.40 per litre.

Increase in price = $5.40 - $4 = $1.40

and increase % = Increase in price/Original price × 100 %

= 1.40/4 × 100 %

= 140/4 %

= 35 %

We will apply the concept of solving some real-life problems by using the formula for finding the increase percent.

Solved examples:

1. The price of rice is increased from $10 to $12.50 per kg. Find the percentage increase in price.

Solution:

Price of rice before = $10

Price of rice now = $12.50

Increase in price = current price – original price

= $12.50 - $10

= $2.50

Therefore, percentage increase in price = Increase in price/Original price × 100 %

= 2.50/10 × 100 %

= 250/10 %

= 25 %

Thus, increase in price= 25 %
