## Percentage For Bank Exam

### What is the Percentage?

**Percentage** means apart from the whole which is generally denominated as 100. Or that part can be said as a part per 100. In general terms, Percentage means part per hundred.

**The percentage** sign ‘%’ derives its meaning from a Latin word called ‘*per centum*‘ which means ‘by the hundred’.

### Percentage Formula

**Percentage Formula** to find the percentage of any number/fraction of its whole number is given below:

**Percentage = (number or fraction / whole number) x 100**

### Percentage Examples

Let’s understand above Percentage formula with the help of some **percentage examples** given below:

**Example 1**: There are 150 students in a class. Out of them, 60 are girls. Find the percentage of girls in the class?

**Solution:** Total students in the class = 150 {**Note**: Given total is always a whole number.}

Girls in the class = 60 {**Note**: Given Number or Fraction of the whole number.}

Percentage of girls in the class = (60 ⁄ 150) × 100 = (600 ⁄ 150) = 40%

**Note**: From the above example it’s clear that we require a clear understanding of **BODMAS** and knowledge of **Maths Tables**. In above example we can see 15 x 4 = 60.

## Percentage Calculation Tricks

Let’s understand **PPercentage For Bank Exam tricks** with the help of two whole numbers 100 and 1000.

### Example of 100

- 100% of 100 is 100.
- 75% of 100 is 75. It’s also three-quarters or 3/4 of the whole number.
- 50% of 100 is 50. It’s also half or 1/2 of the whole number.
- 66.6% of 100 is 66.6. It’s also two-thirds or 2/3 of the whole number.
- 33.3% of 100 is 33.3. It’s also one-third or 1/3 of the whole number.
- 25% of 100 is 25. It’s also a quarter or 1/4 of the whole number.
- 20% of 100 is 20. It’s also one-fifth or 1/5 of the whole number.
- 10% of 100 is 10. It’s also tenth or 1/10 of the whole number.
- 1% of 100 is 1. It’s also a hundredth or 1/100 of the whole number.

### Example of 1000

- 100% of 1000 is 1000.
- 75% of 1000 is 750. It’s also three-quarters or 3/4 of the whole number.
- 50% of 1000 is 500. It’s also half or 1/2 of the whole number.
- 66.6% of 1000 is 666. It’s also two-thirds or 2/3 of the whole number.
- 33.3% of 1000 is 333. It’s also one-third or 1/3 of the whole number.
- 25% of 1000 is 250. It’s also a quarter or 1/4 of the whole number.
- 20% of 1000 is 200. It’s also one-fifth or 1/5 of the whole number.
- 10% of 1000 is 100. It’s also tenth or 1/10 of the whole number.
- 1% of 1000 is 10. It’s also a hundredth or 1/100 of the whole number.

From the above example, it’s easily concluded that finding any given percentage means finding its fraction of the whole number.

## Percentage Calculation Examples

Below are a few examples of percentage calculation:

**Example 1**: Find 25% of 500?**Solution 1**: **Way 1** by applying the **Percentage Calculation Formula**.

=> 500 is the Whole number.

=> Given percentage is 25%. or can be expressed as 25/100

=> Let the number be Y.

As per formula => Percentage = (number / whole number).

Now putting values in formula, we get

=> 25/100 = (Y / 500)

=> Y = (25 x 500) / 100

=> Y = 12500 / 100

=> Y = 125

**Solution 1**: **Way 2** by applying a **fraction logic**.

As we know that 25% is one-fourth of the whole number.

Let Y = 500 / 4 = 125.

From the above two ways of solving percentage problems, we can clearly see that the fraction method is faster and quicker to get results.

## Percentage Calculation Solved Examples

Below are a few solved examples of calculating percentage for bank exam, that are based on **quick tricks to get percentages** instead of taking a longer approach:

**Example 1**: Find 30% of 300.**Solution 1**: For finding 30% it’s will be faster to find 10% and then multiply it by 3 to get 30%.

=> 10% of 300 = 30 {**Note**: it’s easy to divide any number by 10 or simply remove 0 from unit place of whole number.}

=> 30% = 10% x 3 = 30 x 3

=> 90 {Final answer.}

**Example 2**: Find 45% of 400.**Solution 2**: For finding 45% it’ll be very helpful if we find 50% and apply the below logic to get an answer.

=> 50% of 400 = 200 {**Note**: By fraction we can easily half the number.}

Now we’ll find 5% of 400. It can be easily found from 50% that we got in above step. We just need to find tenth part of 200.

=> 5% of 400 = (50% of 400) / 10 = 200 / 10 = 20.

Now the reason of finding 5% is 50% – 5% = 45%

=> 45% of 400

=> (50% of 400) – (5% of 400) {**Note**: Apply BODMAS}

=> 200 – 20

=> 180 {Final Answer}

**Best Approach**: For the above example the best approach we found was to find 50% and get the answer with minimum and easy calculation. It depends on candidates which approach they find easier to solve this question. In the end what matters is the correct answer in minimum time, irrespective of approach.
