Percentage - The word - ‘Percentage’ is a combination per + cent. A comparison by 100 is called percentage. It is the most common topic in the quantitative aptitude section in all government job exams. The percentage is the most important topic because the whole theory of arithmetic is depended on its concept. We have learned it in our school days but here we need some smart approaches to solve the questions. Questions in quantitative aptitude sections of government and competitive exams don’t match much from what we studied in school. Most common types of questions asked in percentages are as follows -

1. How to calculate the percentage of marks

2. Questions based on basic concepts of percentage

3. Questions based on net increase & decrease

4. Questions based on consumption, price & quantity

5. Questions based on ratios

6. Questions based on examination & marks

7. Questions based on elections

8. Questions based on population

9. Questions based on the fractional method

10. Questions based on Venn-diagram

### How to prepare percentages?

• Tables, square, cubes are the prerequisite for the percentages.

• Learn the questions solving using base 100.
