RS Aggarwal Solutions Class 7 Maths Chapter 10 Ex 10.1 – Overview

Introduction

Percentage can be defined as a ratio or a particular number that can be expressed in the form of 100. To find the percentage of any given number, we need to divide the entire number as a whole, and then multiply it by 100. While saying the statement, “80% of a specific number, we meant to say the 80% of it’s whole and not just a given number.

Percentage Formula

To find the percentage value, you have to divide the given value and the total value, then multiply this entire equation by 100.

Percentage Formula = ( Given Value / Total Value ) × 100

Example: 2/5 × 100 = 0.4 × 100 = 40 per cent.

Percentage Difference Formula

Percentage Difference Formula = ( n1 − n2 ) [ ( n1 + n2 ) 2 ] × 100

Where n1 and n2 are the two given values.

Percentage Tricks

The calculation of the percentage is easy and simple. Here is the easiest trick to solve any question that may come across on the percentage topic.
