The percentage is one of the topics from Quantitative aptitude on which fixed questions are asked. Hence, to solve the percentage problems in less time with accuracy, we have provided Shortcuts and tricks to calculate Percentage.
In addition to the shortcut described above, there are several other useful shortcuts for calculating percentages. These include:
To calculate the percentage increase or decrease of a number, you can use the formula: (new value - old value)/old value x 100 = percentage increase/decrease. For example, if the old value is 100 and the new value is 120, the percentage increase would be: (120 - 100)/100 x 100 = 20/100 x 100 = 20%.
To calculate the percentage of a number that is equal to another number, you can use the formula: (number/total) x 100 = percentage. For example, if the number is 10 and the total is 100, the percentage would be: (10/100) x 100 = 10%.
To calculate the percentage of a number that is greater than or less than another number, you can use the formula: (number/reference number) x 100 = percentage. For example, if the number is 10 and the reference number is 100, the percentage would be: (10/100) x 100 = 10%. If the number is greater than the reference number (e.g. 120), the percentage will be greater than 100%, and if the number is less than the reference number (e.g. 80), the percentage will be less than 100%.
Overall, these shortcuts can be useful for quickly calculating percentages in a variety of different situations. It's important to understand the underlying formulas and how to adjust them for different scenarios in order to use these shortcuts effectively
