Shortcut to find percentage of a number is one of the coolest trick which makes maths fun. With this trick you can mentally find the percentage of any number within seconds.

Let us understand a simple concept on percentages here

100% of a number will be the number itself

ex:100% of 360 will be 360

50% of a number will be half of the number

ex:50% of 360 will be 360/2=180

25% of a number will be quarter of the number or half of 50% of the number

ex:25% of 360 will be 360/4 or 180/2=90

10% of a number can be found by shifting the decimal point by 1 place to the left.

ex:10% of 360 will be 36.0

5% of the number is half of 10% of a number

ex:5% of 360 will be 36/2=18

15% of the number will be the sum of 10% and 5% of a number

ex:15% of 360 will be (10% of 360)36+(5% of 360)18=54

1% of a number can be found by moving the decimal point by 2 places to the left.

ex:1% of 360 will be 3.60

Now that we know the concept let us see how we can apply this trick in the below examples

## Examples to apply shortcut to find percentage of a number

**Example 1:** 11% of 550 is?

**Step 1: **Split the number into 2 numbers that we can easily find the percentage of.

We can split 11% into 10% and 1%

**Step 2: **First we find 10% of 550 by shifting the decimal point to the left by 1 place.

We get,

10% of 550=55.0

**Step 3:** Now we need to find 1% of 550 by shifting the decimal point to the left by 2 places.

We get,

1% of 550=5.50

**Step 4:**Adding both the results

we get 10%+1%=55.0+5.50=60.50

**Ans 11% of 550=60.50**

**Example 2:**21% of 250 is?

**Step 1: **21% can be split into 10%+10%+1%

**Step 2:** First we find 10% of 250 by shifting the decimal point to the left by one place

we get,

10% of 250=25.0

**Step 3: **Another 10% of 250 we get

10% of 250=25.0

**Step 4:**Now we need to find 1% of 250 by shifting the decimal point to the left by 2 places.

We get,

1% of 250=2.50

**Step 5:**Adding all the results we get,

10%+10%+1%=25+25+2.50=52.50

**Ans 21% of 250=52.50**

**Example 3:** 61% of 754 is?

**Step 1:**61% can be split into 50%+10%+1%

**Step 2: **First we find 50% of 754 which is half of the number

we get, 50% of 250=377

**Step 3: **First we find 10% of 754 by shifting the decimal point to the left by one place

we get, 10% of 754=75.4

**Step 4:**Now we need to find 1% of 754 by shifting the decimal point to the left by 2 places.

We get, 1% of 754=7.54

**Step 5:**Adding all the results we get,

50%+10%+1%= 377+75.4+7.54=459.94

**Ans 61% of 754=459.94**

**Example 4:** 98% of 850 is?

**Step 1: **98% can be split into 100% – 2%

**Step 2: **We know that 100% of 850 which is 850.

**Step 3: **Now we find 1% of 850 by shifting the decimal point to the left by 2 places

we get, 1% of 850= 8.5

**Step 4:**Now we find 2% of a number,

1% of 850 + 1% of 850=8.5 + 8.5

we get, 2% of 850= 17

**Step 5:**a Subtracting the results we get,

100%- 2%= 850-17=833

**Ans 98% of 850=833**

**Example 5:** 95% of 620 is?

**Step 1: **95% can be split into 100% – 5%

**Step 2: **We know that 100% of 620 which is 620.

**Step 3: **Now we find 10% of 620 by shifting the decimal point to the left by 1 place

we get, 10% of 620= 62

**Step 4:**Now we find 5% of 620 which is half of 10%

62/2= 31

we get, 5% of 62= 31

**Step 5:**a Subtracting the results we get,

100%- 5%= 620-31=589

**Ans 95% of 620=589**

Great explanations.. Thank you so much.

One day when I was finding some trick for % then I came across this wonderful blog . Good work keep it up . God bless you.

Thanks from my heart . Very nice tricks . I am feeling so happy .

Currently you have few follower’s but I am sure one day when people will know about your website .then they definitely liked it . Very very very good tricks .

Ok thats good. But WhAT ABOUT THIS ONE ??

47% of 347 and 63% of 662

the ones you have mentioned were easy because Addition was involved. The places where subtraction is involved..what about them..can you tell any trick about that ?? Nowadays in Bank exams these types have replaced with the ones i gave above.

For 47% of 347 we just have to find out 50% of 347 (173.5) and then find out 1% of 347 (3.47) add it 3 times (3.47+3.47+3.47 =10.41) and subtract it from the result (173.5-10.41)

thn how to calculate 750% of 12…. please expalin

Simply find 12% of 750. both are same only.

Exp: for 750% of 12 = (750/100)*12 which is equal to 12% of 750 = (12/100)*750

0.8% of 779

0.366%of 4880

thank u so mch…:))
