From the mentors at Career Launcher South Ex, Delhi
The Quantitative Aptitude (QA) section in the Common Admission Test (CAT) is one of the most challenging yet rewarding parts of the exam. With strong concepts, smart techniques, and consistent practice, you can turn it into your biggest strength. CAT coaching center near South Ex, here's a step-by-step guide to help you master CAT Quant effectively.
Step 1: Understand the CAT Quant Syllabus
The QA section is designed to test your mathematical aptitude and logical reasoning through high school-level math concepts.
Key Topics to Cover:
Arithmetic
-
Percentages, Profit & Loss, Ratio & Proportion
-
Simple & Compound Interest, Time & Work, Time-Speed-Distance
Algebra
-
Linear & Quadratic Equations, Inequalities, Logarithms, Functions
Number System
-
Factors, LCM & HCF, Remainders, Divisibility Rules
Geometry & Mensuration
-
Triangles, Circles, Polygons, Coordinate Geometry
Modern Math
-
Permutation & Combination, Probability, Set Theory
Step 2: Master Conceptual Understanding
Start by building a strong foundation in each topic.
-
Use standard reference books like Arun Sharma’s Quantitative Aptitude for CAT or Nishit K. Sinha’s Pearson Guide.
-
Create a formula sheet for each chapter and revise it regularly.
-
Focus on clarity, not shortcuts—shortcuts work only after you understand the basics.
Sample Question – Number System
Q: Find the unit digit of 234⁵⁶⁷
(a) 2 (b) 4 (c) 6 (d) 8
Solution:
Unit digit of 234 is 4. Powers of 4 cycle as: 4, 6, 4, 6.
567 mod 2 = 1 → Pick the 1st number in the cycle = 4
Answer: (b) 4
Step 3: Solve CAT-Level Problems
Once you’re clear on concepts, move to problem-solving.
-
Solve 15–20 questions every day
-
Learn shortcut methods for speed and efficiency
-
Practice sectional tests to simulate time pressure
Sample Question – Time & Work
Q: A and B can complete a work in 12 days and 16 days respectively. How long will they take to finish the work together?
(a) 6.86 days (b) 7.2 days (c) 6.85 days (d) 7 days
Solution:
A’s rate = 1/12, B’s rate = 1/16
Combined rate = (1/12 + 1/16) = 7/48
Time = 48/7 = 6.86 days
Answer: (a) 6.86 days
Sample Question – Algebra
Q: If x+1x=5x + \frac{1}{x} = 5x+x1=5, find x2+1x2x^2 + \frac{1}{x^2}x2+x21
(a) 21 (b) 23 (c) 25 (d) 27
Solution:
Square both sides:
x2+1x2+2=25x^2 + \frac{1}{x^2} + 2 = 25x2+x21+2=25
x2+1x2=23x^2 + \frac{1}{x^2} = 23x2+x21=23
Answer: (b) 23
Step 4: Take Mock Tests & Analyze Performance
Mocks are essential to simulate exam pressure and refine your strategy.
-
Take at least one full mock test every week
-
Spend time analyzing errors and identifying weak spots
-
Use timers in practice to boost your speed and focus
Step 5: Stay Consistent & Motivated
The real key to Quant mastery is daily discipline.
-
Solve at least 20 QA questions every day
-
Join peer groups or discussion forums to explore alternate solving approaches
-
Follow a structured revision plan to refresh old concepts regularly
Conclusion
CAT Quant doesn’t demand brilliance—it demands strategy, practice, and patience. Focus on building concepts, solving consistently, and learning from your mistakes. With the right approach, your Quant score can become a game-changer.
