4. Learn the Divisibility rules as it will be beneficial for you to do the calculation in no time.

Numbers | If a Number |
---|---|

Divisible by 2 |
End with 0,2,4,6,8 are divisible by 2 |

Divisible by 3 |
Sum of its digits is divisible by 3 |

Divisible by 4 |
Last two digit divisible by 4 |

Divisible by 5 |
Ends with 0 or 5 |

Divisible by 6 |
Divides by Both 2 & 3 |

Divisible by 8 |
Last 3 digit divide by 8 |

Divisible by 10 |
End with 0 |

Divisible by 11 |
[Sum of its digit in odd places-Sum of its digits in even places]= 0 or multiple of 11 |

5. Learn the different tricks that can really help you to fasten your calculation like **Digital sum method that is explained below:**

- In this method, we get the
**digit-sum of a number by adding across the number**. for eg,**the digit-sum of 13022**is 1+3+0+2+2**=**8 **The trick is to always reduce the digit-sum to a single figure. for eg, the digit-sum of 5264 is 5+2+6+4=17****and further reduce it to single figure i.e 17**is reduced to a single figure i.e.**digit sum of 1+7=8**.- What is important to note here is the fact that i
**n adding across a number we may drop out 9, 9 doesn’t count on digit sum.**eg1: digit sum of**9901is (0+1)= 1 or**eg2:**digit sum of 279 is (2+7+9)= 0**here digit sum of**(2,7) makes 9**. - Even for
**decimals, the process remains the same**but we don’t pay**attention to the decimal points**. The digit sum of**6.256 is (6+2+5+6)=19**, neglect 9=**digit sum is 1** - We can apply this trick for
**addition, subtraction, multiplication, division**. You can straight away eliminate the options based on this method.
