#### Number Divisibility Rules

**Divisibility Rules of whether a number is divisible by 2, 3, 4, 5, 6, 8, 9 and 10**

Number | Rule | Example |
---|---|---|

2 | Last digit in the number is even. | 14, 102, 118, 560 all end in even numbers, so all are divisible by 2. |

3 | Sum of the digits of the number is divisible by 3. | The sum of the digits of 396 is 3+9+6 = 18 which is divisible by 3, so 396 is divisible by 3. |

4 | Number formed by the last 2 digits is divisible by 4. | Last 2 digits of 1424 is 24, which is divisible by 4, so 1424 is divisible by 4. |

5 | Last digit is 0 or 5 | 35, 90, 475 |

6 | Number is even and divisible by 3. | 144 is even and is divisible by 3 (sum of digits 1+4+4 = 9, divisible by 3), so 144 is divisible by 6. |

8 | Last 3 digits divisible by 8 or Last 3 digit is 000 | Last 3 digits of 83400 is 400 which is divisible by 8. Last 3 digits of 1000 is 000 hence it is divisible by 8 |

9 | Sum of the digits of the number is divisible by 9. | Sum of the digits of 1485 is 1+4+8+5 = 18 which is divisible by 9, so 1485 is divisible by 9 |

10 | Last digit is 0 | 90, 120, 680 |

**Number Divisibility Rules**

#### Mental Ability – Competitive Exam Preparation – Number Series by adding fixed number – NTSE, NCO, NSO, IMO and other Competitive Exams

## Mental Ability – Competitive Exam Preparation – Number Series by adding fixed number – NTSE, NCO, NSO, IMO and other Competitive Exams

The sequence or series of numbers created by adding fixed number :

**5 , 7 , 9 , 11 , 13 etc**– Number sequence obtained by adding fixed number 2**6, 11, 16, 21, 26 etc**– Number sequence obtained by adding fixed number 5

Similarly number sequence can be obtained by adding two fixed numbers alternatively or by adding two fixed numbers after repeated series. Example below:

**5, 7, 10,12, 15, 17, 20 etc **– This number sequence is formed by adding 2 and 3 alternatively

**5, 6, 7, 9, 11, 13, 16, 19, 22 etc** – This number sequence is formed by adding fixed number 1 , 2 and 3 after regular interval i.e after 3 numbers

Below is some questions to practise this. Please leave your answers in comment box on this page or write to us on abhyas.practise@gmail.com.

We will revert back with right answers at the earliest
