Percentage forms the backbone of quantitative aptitude. In the UP Police Constable exam, understanding and quick application of percentage concepts can give you a significant edge. Here's why:
Before diving into short tricks, it's essential to have a clear understanding of what percentage is. 'Per cent' literally means 'per hundred' or 'out of every hundred'. It's a way of expressing a number as a fraction of 100.
These basic conversions are the first step towards mastering percentage short tricks. Memorizing common fraction-percentage equivalents (e.g., 1/2 = 50%, 1/3 = 33.33%, 1/4 = 25%, 1/5 = 20%, 1/6 = 16.66%, 1/7 = 14.28%, 1/8 = 12.5%, 1/9 = 11.11%, 1/10 = 10%) can dramatically speed up your calculations during the exam. Unictest provides comprehensive study material and practice questions to help you solidify these foundational concepts. Regular practice is key to making these conversions second nature, allowing you to focus on applying the actual short tricks to solve problems more efficiently in the UP Police Constable 2026 exam.
| Percentage Topic (प्रतिशत विषय) | Expected Questions (अपेक्षित प्रश्न) | Difficulty Level (कठिनाई स्तर) | Key Concepts (प्रमुख अवधारणाएँ) |
|---|---|---|---|
| Basic Percentage Calculations (मूल प्रतिशत गणना) | 2-3 | Easy to Moderate | Conversion, A is % of B, Finding X% of Y |
| Percentage Increase/Decrease (प्रतिशत वृद्धि/कमी) | 1-2 | Moderate | Price changes, Population, Salary changes |
| Profit & Loss (लाभ और हानि) | 2-3 | Moderate to Hard | Cost Price, Selling Price, Discount, Markup |
| Simple & Compound Interest (साधारण और चक्रवृद्धि ब्याज) | 2-3 | Moderate to Hard | Principal, Rate, Time, Amount |
| Data Interpretation (डेटा व्याख्या) | 3-5 | Moderate to Hard | Percentage comparison, Ratio, Average from charts |
| Successive Percentage Change (क्रमिक प्रतिशत परिवर्तन) | 1-2 | Moderate | Net effect of multiple changes |
Here are some of the most effective percentage short tricks that every UP Police Constable aspirant should master:
Instead of multiplying and dividing by 100, break down the percentage. For example, to find 70% of 250:
70% of 250 = (50% + 20%) of 250
= (1/2 * 250) + (1/5 * 250)
= 125 + 50 = 175.
Or, 70% of 250 = 7 * 10% of 250 = 7 * 25 = 175. This mental math approach is very fast.
If a value 'A' is increased by x%, the new value is A * (100+x)/100. If decreased by x%, it's A * (100-x)/100.
Short Trick: For a percentage increase of x%, the multiplying factor is (1 + x/100). For a decrease of x%, it's (1 - x/100).
Example: If a price of ₹400 is increased by 20%, new price = 400 * (1 + 20/100) = 400 * 1.2 = ₹480.
When a value is changed by x% and then by y%, the net percentage change can be found using the formula: Net Change = [x + y + (xy/100)]%.
Example: A laptop's price is increased by 10% and then decreased by 10%. Net change = [10 + (-10) + (10 * -10)/100]% = [0 - 100/100]% = -1%. (1% decrease). This trick is invaluable for problems involving population changes or price fluctuations.
This is a fundamental concept. The formula is (A/B) * 100%.
Example: If 30 marks are obtained out of 50, what is the percentage? (30/50) * 100% = 60%.
Short Trick: Simplify the fraction first. 30/50 = 3/5. We know 1/5 = 20%, so 3/5 = 3 * 20% = 60%.
If A is x% more than B, then B is [(x / (100+x)) * 100]% less than A.
If A is x% less than B, then B is [(x / (100-x)) * 100]% more than A.
Example: If A's salary is 25% more than B's, then B's salary is [(25 / (100+25)) * 100]% less than A's = (25/125)*100% = (1/5)*100% = 20% less.
These tricks, when practiced regularly, become intuitive and help you solve problems with great speed. Unictest offers a wide range of practice questions categorized by trick type, helping you master each one for the UP Police Constable 2026 exam.
Beyond the basic tricks, applying percentage concepts in word problems requires a slightly more nuanced approach. For instance, problems involving population growth/decay, examination pass/fail scenarios, or expenditure and savings often combine multiple percentage changes. For these, a good understanding of the base value and how it changes with each percentage is key. Using a base of 100 or 1000 for calculation often simplifies these problems greatly.
