## FAQs on Tips & Tricks: Percentage Video Lecture - Tips & Tricks for Government Exams - Bank Exams

 1. What is a percentage?
Ans. A percentage is a number or ratio expressed as a fraction of 100. It represents a proportion or fraction out of 100. For example, 50% means 50 out of 100.
 2. How do you calculate a percentage increase or decrease?
Ans. To calculate a percentage increase or decrease, you need to find the difference between two values and divide it by the original value. Then multiply the result by 100 to get the percentage. For example, if the original value is 100 and it increases to 120, the percentage increase would be ((120-100)/100) * 100 = 20%.
 3. How do you calculate a percentage of a number?
Ans. To calculate a percentage of a number, multiply the number by the percentage and divide it by 100. For example, to find 20% of 50, you would calculate (20/100) * 50 = 10.
 4. How do you calculate the percentage difference between two numbers?
Ans. To calculate the percentage difference between two numbers, you need to find the absolute difference between the two values and divide it by the average of the two numbers. Then multiply the result by 100 to get the percentage. For example, if the two numbers are 80 and 100, the percentage difference would be ((100-80)/((80+100)/2)) * 100 = 25%.
 5. How do you find the original value after a percentage increase or decrease?
Ans. To find the original value after a percentage increase or decrease, you need to divide the final value by 1 plus (or minus) the percentage. Then multiply the result by 100. For example, if there was a 20% decrease from a final value of 80, the original value would be (80/(1-0.20)) * 100 = 100.
