Finding percentages is very important chapter in mathematics as well as in our day to day life,percentage finding is a general and very very important thing in business analysis and scientific applications. as a student you know you will get percentage of marks earned in a exam in your school.
In sports as a team analyst find the percentage of success of a individual player in a tournament .A shopkeeper estimates to sell the product to certain amount to get desired percentage of profit, so such examples are common with anybody's observation.So knowing the percentage is not only important ,it is a necessity with finding percentages. we will know on which area we have to improve to get good results.knowing percentages as a person is very essential.
So how to find percentage:
x is what percent of y =(x/y) * 100
Example : jhon is scored 8 out of 10 in a subject than his percentage of marks in that subject is
Percentage of marks of jhon=(8/10) * 100 = 80
So jhon got 80 percentage of marks in the subject.
* Let quarter part of the pizza means 1/4 th part of pizza and assume the pizza as a whole as 1
So remaining pizza part is 1- 1/4 =3/4
3/4 in percentage =3/4 * 100 =75 %
Tip for you: Multiply given fraction with 100, we get percentage.
Profit Percentage:
If an item is sold for more than its buying cost, then it is known as that the item have been sold at a profit.
If the profit is often uttered as a percentage of the cost price, then it is called as the percentage profit. In this article we are going to discuss about the formula of profit percentage and the example problems to solve the profit percentage.
The formula used to find the profit and the profit percentage is explained below.
For finding the profit percentage first we need to find the profit of the product.
The formula used to find the profit is:
'"Profit" = "selling price (SP)" - "Cost price (CS)"'
The formula used to find the profit percentage is:
'"Profit %" ="Profit" / "Cost price" xx100%'
Examples:
Example 1: If a shopkeeper want to sold a cooler for 150 dollar and actually he got that cooler for 125 dollar(cost price) then, what is his profit percenage?
Solution:
Cooler cost price=125$
Cooler selling price=150$
Profit = Selling price - Cost price
profit=25$
Therefore, profit percentage= (profit/cost price) x 100=(25$/125$) *100 =(1/5) * 100 =20 %
So shopkeeper will get 20% profit, if he sold the cooler for $150.
Example 2: Generally in hollywood there are 750 flop pictures out of 1000 pictures per year. so the success rate of flims in hollywood is?
Solution:
Number of successful pictures =1000-750=250
sucess rate = (successful pictures/total pictures) * 100 = (250/1000)*100 =25%
So success percentage is 25 %
Example 3: 25 is what percentage of 50?
Solution:
=(25/50) * 100
=(1/2) * 100
=50 %
So 25 is 50% of 50
Example 4: in school test student has three subjects math,science and social and a student got 85, 80,90 in math , science and social subjects respectively out of 100 marks in each subject than what is his percentage of marks on that test?
Percentage = (sum of marks earned by the student / total marks ) * 100
=(85+80+90) / 300
=255/300
=85%
So student got 85% of marks on that test
Example 5: A house was bought for 80 000 dollar and is sold for 95 000 dollar. Find the percentage profit?
Solution:
Cost price = $80000
Selling price = $ 95000
Profit = SP - CP
= $95000 - $ 80000
= $ 15000
Profit % = (15000) / (80000) *100%
= 18.75%
Thus, the percentage profit is 18.75%.
Example 6: A car was bought for 300 000 dollar and is sold for 350000 dollar. Find the percentage profit?
Solution:
Given:
Cost price = $300000
Selling price = $ 350000
Profit = SP - CP
= $300000 - $ 350000
= $ 50000
Profit % = (50000) / (300000) *100%
= 16.66%
Thus, the percentage profit is 16.66%.
