**Concept of Percentage**: Percent is a combination of two words. Per and Cent, Per means out of and Cent means 100. Thus percent means out of every hundred. The symbols used for percent is %.

9% means 9/100.

100% means 100/100

Lets us take some examples to calculate the percentage of marks.

**Example 1**:

In a class test if you got 7.3 marks out of 10. Find the percentage of marks you got?

Solution: Total Mark = 10. Mark obtained = 7.3.

Required Percentage = Marks obtained/Total Marks Ã— 100%

= 7.3/10 Ã— 100%

= 73/100 Ã— 100%

= 73%

**Example 2: **

If you got 75 marks out of 80 in a mathematics test. Find the percentage of marks you got?

**Solution:** Total marks = 80. Marks obtained = 75.

Required percentage = Marks obtained/Total marks Ã— 100%.

= 75/80 x 100 %

= 75/4 x 5 %

= 375/4 %

= 93.75 %

**Note:**

**Example 3: **

If a student got 99 marks out of 150 in science exam. Find the required percentage?

**Solution**: Total marks = 150. Marks Obtained = 99.

Required percentage = 99/150 Ã— 100%

= 99/15 x 10%

= 990/15%

= 66%

**Note:**

**Example 4: **

In the final examination, Ram scored marks in each subject are given below:

Subject |
Marks obtained |
Total Marks |

English | 75 | 100 |

Math | 95 | 100 |

Science | 93 | 100 |

Hindi | 79 | 100 |

S.St | 90 | 100 |

Computer | 91 | 100 |

Find the total percentage.

**Solution**: Total marks = 600. Total marks obtained = 523.

Required Percentage = 523/600 Ã— 100%

= 523/6%

= 87.16%

**Note:**

At last, we conclude that the percentage is a very very important and basic topic. It is used in everyday life like discounts in shops, bank interest rates, etc.
