How to solve Percentage Questions for Aptitude-based Exams 2024?: Tips

The percentage questions in an Aptitude Exam can be solved by various methods and tricks, but to use those methods and tricks, you should be aware of the fractional value of the percentage. So that we can convert the percentage into the fractional value, solve the question easily and then convert that fractional value into the ratio.

For example:

Any number XYZ is increased by 25%. So, we should be aware of the fractional value of 25%, i.e. ¼. Here, 4 is the base value. Initially, let us assume that the number is 4, and you have increased it by 1, so the ratio will be 4:5. So if you know the exact value of any of them, 4 or 5. So, you can calculate the other value easily or else you know the exact value of their difference, i.e. 1 unit.

The fractional value of 25% is ¼, the fractional value of 20% is 1/5, and the fractional value of 33.33% is 1/3.

How to find 100% of a number - 100% of a number means the whole thing; hence, 100% of any number is just the number itself.

Example: 100% of 5 is 5; 100% of 740 is 740.

How to find 50% of a number - 50% of a number means half of that number. So, when you are finding 50% of any number, just divide it by 2.

Example: 50% of 86 is 43; 50% of 7/2 is 3.5

How to find 25% of a number - 25% of any number is 1/4 of that number. Hence, you need to divide the number by 4 to find 25% of the number.

Example: 25% of 84 is 21; 25% of 15 is 3.75.

How to find 20% of a number - 20% of a number is 1/5 of that number, which means you must divide the number by 5 to get 25% of that number.

Example: 20% of 250 is 50; 20% of 41 is 8.2

How to find 10% of a number - 10% of any number is 1/10 of the number. You must divide the given number by 10 to find 10% of that number.

Example: 10% of 8 is 0.8; 10% of 30 is 3.

How to find 200%, 300% and so on of a number - To find 200%, 300% or any multiples of 100, you need to remove the two zeroes and multiply with the left-out numeral.

Example: 300% of 40 is 120 (300 * 40 = 120)
