Tricks To Speedup Your Maths Ability.

Here are some easy way to solve aptitude or mathematics questions.


1. An easy way to multiply numbers which is nearer to 100,1000,10000 etc..

Now let us multiply 6573848 with 999
So, we can take 6573848(1000-1)

You can follow the similar way for other nearer numbers, if its greater than 1000

Let us consider 8532*1002

2. How to find the least number to be added with another number to make that number to be exactly divided by some number?

Step 1: Divide the first number with the second number
Step 2: Take the reminder and subtradt with the second number.
Step 3: The answer of that subtraction is the least number.

Now let us see with an example
Find the least number to be added to 4000 to obtain a number exactly divisible 19?

On diving 4000 by 19, we get the reminder as 10.
then sub 19-10=9
So the answer is 9.
If 9 is added with 4000, we get 4009
When we divide 4009/19=211.

I hope you can understand this. If you have any other easy method post that in the comments below 🙂
