## Permutation example 3 with tricks

Shortcut tricks on permutation are one of the most important topics in exams. Time takes a huge part in competitive exams. If you know how to manage time then you will surely do great in your exam. Most of us miss this thing. We provide examples on Permutation shortcut tricks here in this page below. All tricks on permutation are provided here. Visitors please read carefully all shortcut examples. These permutation example will help you to understand shortcut tricks on Permutation.

Before starting anything just do a math practice set. Choose any twenty math problems and write it down on a page. Solve first ten math problems according to basic math formula. You also need to keep track of timing. After solving all ten math questions write down total time taken by you to solve those questions. Now go through our page for permutation shortcut trick. After finishing this do remaining questions using Permutation shortcut tricks. Again keep track of Timing. The timing will be surely improved this time. But this is not enough. You need to practice more to improve your timing more.

### Few Important things to Remember

Math section in a competitive exam is the most important part of the exam. That doesn’t mean that other topics are less important.

You should do your math problems within time with correctness, and only shortcut tricks can give you that success. Again it does not mean that you can’t do maths without using shortcut tricks. You may do math problems within time without using any shortcut tricks. You may have that potential.

But, so many people can’t do this. For those we prepared this permutation shortcut tricks. Here in this page we try to put all types of shortcut tricks on Permutation. But we may miss few of them. If you know anything else rather than this please do share with us. Your little help will help so many needy.

We learn what is permutation? So now we need more knowledge on this using more practice Permutation Example of permutation with tricks which help in exams fast and efficiently. Again we talk about permutation that permutation is a various or several given arrangement of numbers or several things where we taking some or all at a time. Here is some examples are given below.

How to Solve
First of all we need to know how many vowel are in the given word.
Here is 2 vowels, that is, A and E.
Then we count the consonant, that is 2.

Now, we count the number of vowels as a single unit.
This means vowel A and E count as a single unit and add it with consonant so we have total 3 unit.
(2 consonant + two vowel as single unit )
= 3! x 2! (two vowel).

Now, if we subtract this value from the total number of ways possible ( without the vowel not together condition ), then we get the total possible ways that the vowels will not come together.
So, 4! – ( 3! x 2! )
= 24 – 12
= 12.

How to Solve
First of all we need to know how many vowel are in the given word.
Here is 3 vowels, that is, U, A and E.
Then we count the consonant, that is 2.

Now, we count the number of vowels as a single unit.
This means vowel U, A and E count as a single unit and add it with consonant so we have total 3 unit.
(2 consonant + three vowel as single unit )
= 3! x 3! (three vowel).

Now, if we subtract this value from the total number of ways possible ( without the vowel not together condition ), then we get the total possible ways that the vowels will not come together.
So, 5! – ( 3! x 3! )
= 120 – 36
= 84.
