Percentages are the most fundamental topic in CAT Arithmetic, forming the base for Profit & Loss, Simple & Compound Interest, and Data Interpretation. This guided path will teach you the core concepts and advanced shortcuts needed to solve these problems with speed and accuracy.
Start with the basics: converting between percents and fractions, and mastering the three core problems (finding the part, percent, or whole).
Memorize and practice using fractional multipliers for common percent increases and decreases. This is a critical speed-boosting technique for the CAT.
Memorize the multipliers for decreases.
Understand the principle of "growth on growth." This visualizer is the key to mastering both compound interest and successive percent changes.
The CAT loves this trap. Use our interactive demo to see why a +X% and a -X% change don't cancel out, and learn the logic to solve these problems quickly.
Now that you understand the trap, learn the specific formulas required to perfectly reverse an initial percent increase or decrease.
Learn the fundamental vocabulary of Profit & Loss and the relationship between Cost Price, Markup, and Selling Price.
Tackle classic CAT problems involving successive discounts, finding overall profit/loss after multiple sales, and scenarios with faulty weights.
