# Percentage

A percent is nothing but a fraction having 100 in it’s denominator. When a number is expressed in the percent form, it is called percentage. It is derived from a Latin word Per centum, and it’s denoted as %.

Let’s take some example to discuss more on the basics of percentage. John got 86 marks out of 100 in a math exam, then the percent of mark in mathematics = 86100 = 86 %

Bob got 91 marks out of 100 in the same exam, then the percent of mark = 91100 = 91%
Since 91% is greater than 86%, we conclude that Bob’s performance is better than John in mathematics exam. The use of percent makes comparison easier as it is just like comparing whole numbers.

A. 6%
B. 10%
C. 60%
D. 90%

A. 8 %
B. 15 %
C. 27 %
D. 35 %

Explaination:

Students passed in English = 80%
Students passed in Math’s = 85%
Students passed in both subjects = 73%
Then, number of students passed in at least one subject
= (80+85)-73
= 92%. [The percentage of students passed in English and Maths individually, have already included the percentage of students passed in both subjects. So, We are subtracting percentage of students who have passed in both subjects to find out percentage of students at least passed in one subject.]

Thus, students failed in both subjects = 100-92 = 8%.
