INTRODUCTION
Mathematics is a language of numbers and symbols. One of the most important symbols that
we use on a daily basis is % (percent). When we receive our report card, we see the percentage
obtained. For example, if a student obtains 90%, it means that he overall scored 90 parts from
100. In this chapter, we shall learn the concept of percentage and solve the problems based on it.
PERCENTAGES
The term ‘per cent’ means ‘for every hundred’.
A fraction, in which the denominator is 100, is a
percentage. The denominator, i.e., 100 is denoted by a
special symbol %, which is read as per cent.
Examples: 10/100 = 10
