Calculate : of 45 m (a) 33 % of 15 kg (b) 45% of 200 (e) 55% of 1 year d) 75% of 25000 (f) 2.5% of 4000 nor cent is.
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 %
