Simple and Shortcut Trick & Concept to Solve Percentage

                                             
                                              Percentages

Many times it happned that we trying to find the percentage through a traditional method, we will get the percentage, but it will take some time to find perfect percentages and in any competitive exam "Time is very much important to make the good score".

So in this article We are going to see the shortcut method to find the Percentage(%) of any number with Example.

For this method we need to understand the Table Below.




Example. ( 1)

So here we will see the first example

1 % of 932 : for 1 %, we have to move the two Decimal point like  9.32

In the example we are on the point to find out the 1% of this given number 932..
so to find out the 1% of 932 we just shift the decimal point by 2 plces..

1) If we shift number by 1 decimal place our number will became...93.2, its 10%.
2) If we shift number by 2 decimal place our number will became...9.32, its 1%.

so guys till now you are master of percentage(%) to find the 1%  of any given number and at this stage if any cute girl ask question to u what is the 1% of any number u can answer her question and can give her a great impression, [and who knows u will get your dream girl by mean of your latent of %]

we will see some other example, by that we can understand and find the percentage easily.

10 % of 932 : Here Move the one Decimal Point = 93.2.

5 % of 932 : Multiply 1 % by 5= 9.32 × 5 = 46.6
or Divide 10 % by 2 =  9.32/2 = 46.6

50 % of 932 : Divide the value by 2.  = 932/2 = 466.

25 % of 932 : Divide 50 % by 2. = 466/2  = 233.

75 % of 932 : 50 % + 25 % = 466 + 233 = 699.

100 % of 932 : It doesn’t change any no. = 932.


 (2) :.  5 % 420

To get 5 % of 420, we can get it by two method.
1st make a 1 % of 420 = 4.2 & multiply it by 5 = 4.2 × 5 = 21
Or 2nd take 10 % of 420 = 42 & Divide by 2 = 42/2 = 21.

(3) 9 % 420 = 10 % - 1% = 42 – 4.2 = 37.8

Some difficult Problem

(4) 43.5 % of 20  This like some kind difficult to find percentage. But its not, we can implement some trick by that we can easily find out the percentage, Lets see.

Remember X % of Y is equal to Y % of X

Then 20 % of 43.5  =  10 % of 43.5 = 4.35 by moving two Decimal point.
To find the 20 % of 43.5, multiply 10 % of 43.5 into 2 = 4.35 × 2 = 8.70
So we can say 43.5 % of 20 = 8.70.

We can solve any Difficult question of the percentage, All you need to do is just Factorize the Percentage (%) in a proper manner.
75 % can be factorize in to 50 % + 25 % = 75 % or 100 % - 25 %
19 % can be factorize into 20%  - 1 %
23 % can be factorize into 20% + 3%
Or Divide the no by 2 for 25 % - 2 % = 23 %
So this is the simple method of finding the Percentages (%) of any value within seconds.
