Just because the Numerical Ability section is worth 15 marks, you won’t leave it out. Look, during exam time, each marks matter. So we advise you to prepare this section with the same focus and dedication as you are giving to the reasoning and general knowledge sections. To help you with that, we have provided free Delhi Police Constable numerical ability topic tests. These tests will help you work on your weak topics deeply in very little time. Along with that, we have also mentioned most scoring topics and provided their topic tests.
Most Scoring Topics in Delhi Police Constable Numerical Ability Section
SSC will ask only 15 questions from the math section, which is good news! You only need to master the arithmetic portion. We have broken down the highest-scoring and most repeated areas, and along with that, we have provided free topic tests. Get familiar with the concept, learn the shortcuts, and then attempt the test immediately to lock in that topic’s score.
1. Number System
Why It’s Important: The Number System is the foundation of all arithmetic. Questions are factual and often involve quick checks of divisibility rules or basic number properties. If your basics are weak here, every other topic will be difficult.
Key Focus:
- Divisibility Rules: Master the rules for 3, 4, 8, 9, 11. These rules help you eliminate options quickly.
- Unit Digit Concept: Learn how to find the unit digit of large products or powers—a very common and fast-scoring question type.
- Fractions and Decimals: Practice quick comparison of fractions and solving simple problems involving decimals.
- Square Roots and Cube Roots: Try to memorize squares up to 30 and cubes up to 20 to save time on basic calculations.

2. Simplification
Why It’s Important: This topic tests your application of the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction). The challenge isn’t the difficulty but the risk of making small calculation errors when dealing with multiple operations.
Key Focus:
- BODMAS Mastery: Practice sums that involve brackets, division, multiplication, and negative numbers.
- Approximation: Learn to round off numbers quickly to simplify complex calculations without losing significant accuracy.
- Percentage/Fraction Conversion: Instantly convert common percentages (like 33.33\%, 16.66\%) into their fractional equivalents (e.g., 1/3, 1/6) to solve faster. This technique is a massive time-saver.

3. Percentage, Profit and Loss, and Discount
Why It’s Important: These three topics are completely interlinked and often account for about 4-5 questions out of the total 15. These are real-life-based problems, making them practical but tricky if you rely only on long formulas.
Key Focus:
- Percentage Basics: Learn the ‘A is what percent of B’ type questions and successive percentage changes.
- Profit & Loss Tricks: Use the ratio method (Cost Price: Selling Price) to solve P&L questions without using 100 as the base value repeatedly.
- Discount & Marked Price (MP): Understand the relationship between MP, Discount, and SP. Practice questions involving two successive discounts—a very frequent SSC pattern.

4. Ratio and Proportion
Why It’s Important: Ratio is another foundational topic that acts as a base for topics like Age Problems, Partnership, and even Time and Work. If you solve problems using ratios instead of equations, you save time instantly.
Key Focus:
- Basic Ratio Combination: Practice combining three or more ratios (e.g., if A:B = 2:3 and B:C = 4:5, find A:B:C).
- Proportionality Rules: Understand Direct and Inverse Proportion and their applications in mixing problems.
- Age and Partnership Problems: Use the ratio concept to solve these quickly, avoiding complex linear equations.

5. Time and Work / Time, Speed, and Distance (TSD)
Why It’s Important: These are problem-solving topics that test logic as much as calculation. They are guaranteed to appear and require specific logical approaches.
Key Focus on Time & Work:
- LCM Method: Always use the LCM (Least Common Multiple) method to find the total work. Forget the old formula method.
- Efficiency: Practice questions involving different efficiencies (A is twice as efficient as B) and working alternately.
Key Focus on Time, Speed, and Distance:
- Conversion: Master the quick conversion between km/hr and m/s (multiply by 5/18 or 18/5).
- Relative Speed: Understand the concept of relative speed for train and boat problems (same direction vs. opposite direction).

How Toppers Master Math Speed
Toppers don’t just solve problems; they analyze how they solve them. When you finish one of our free topic tests, focus on these three things:
- The Accuracy Score (The Concept Check): If you get a question wrong, it means there’s a conceptual gap, not just a calculation mistake. For example, if you missed a time, speed, and distance question, did you forget the relative speed concept, or did you mix up the units? The test solution will point you back to the exact rule you need to re-learn.
- The Time Metric (The Efficiency Check): Did you take 90 seconds for a simple Percentage problem? Even if you got it right, that’s a failure of efficiency! Our analysis shows you the time taken per question. If you are taking more than 40-45 seconds for an arithmetic question, you are using a long method. Find the shortcut and practice it immediately.
- The Formula-vs-Logic Trap (The Strategy Check): In the solution section, compare your method with the provided one. Are you using a long algebraic equation when a simple Ratio Method would solve it in two lines? Train your brain to pick the fastest logical approach, not just the formula you remember first.
