Few examples on percentage shortcuts is given in this page below. We try to provide all types of shortcut tricks on percentage here. Visitors please read carefully all shortcut examples. These examples here will help you to better understand shortcut tricks on percentage.

Before doing anything we recommend you to do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Solve first ten math problems according to basic math formula. You also need to keep track of timing. After finish write down total time taken by you to solve those ten maths. Now practice our shortcut tricks on percentage and read examples carefully. After doing this go back to the remaining ten questions and solve those using shortcut methods. Again keep track of the time. You will surely see the improvement in your timing this time. But this is not all you want. You need to practice more to improve your timing more.

We all know that the most important thing in competitive exams is Mathematics. That doesn’t mean that other topics are less important. You can get a good score only if you get a good score in math section. A good score comes with practice and practice. All you need to do is to do math problems correctly within time, and you can do this only by using shortcut tricks. But it doesn’t mean that you can’t do math problems without using any shortcut tricks. You may have that potential to do maths within time without using any shortcut tricks. But so many other people may not do the same. For those we prepared this percentage shortcut tricks. We try our level best to put together all types of shortcut methods here. But if you see any tricks are missing from the list then please inform us. Your little help will help others.

 


Example #1
The sum of 40% of a number and 25% of that same number is 1599. What would be the 75% of that number?

  1. 1705
  2. 1785
  3. 1845
  4. 1995

Answer: Option (C)
How to Solve
Let, the number is P.
(P x 40 / 100) + (P x 25 / 100) = 1599
P = 2460
So, 75% of the number is = 2460 x 75 / 100 = 1845.

Example #2
Difference between 75% of a number and 43% of same number is 6400. What would be the 8% of that number?

  1. 1000
  2. 1200
  3. 1400
  4. 1600

Answer: Option (D)
How to Solve
75% – 43% = 6400
32% = 6400 = 20000
So, 8% of the number is = 20000 x 8 / 100 = 1600.

Example #4
Bijoy invest his money from his savings in different ways. He invest 30% on buying books, 10% on nutrition, 15% on wages and 22% on purchase a bike and after that all expenditure he saved Rs.4600/-. Find how much he spent on bike?

Answer: Option (B)
How to Solve
Let, the total income of Bijoy is X.
Total expenditure from income X x ( 30% + 10% + 15% + 22% ) = X x 77%
Total savings = X x 23%
X = 4600 x 100 / 23 = 20000

Expenditure on Bike = 22%
So, 20000 x 22 / 100 = 4400.

Example #10
In an party election between two candidates, one got 45% of the total valid votes. 20% of the votes were invalid. If the total number of votes was 7500, the number of valid votes that the other candidate got was?

  1. 3500 Votes
  2. 3300 Votes
  3. 5300 Votes
  4. 4800 Votes

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
Total number of votes are 7500.
Number of valid votes are 80%.
Or we can say (80 / 100) x 7500 = 6000.

Candidate One got 45% of the total valid votes.
So, Other valid votes got by other candidate is (100% – 45%) = 55%.

So, the other candidate got,
(55 / 100) × 6000 = 3300 votes.
The total number of valid votes by the other candidate got is 3300.

Candidate A got 64% votes and
Candidate B got (100% – 64%) = 36% votes.

Difference between two candidates are (64% – 36%) = 28%
Or we can say 28% = 476.

So, the total votes are
476 x 100 / 28 = 1700.
