Key pointers to crack Quantitative Aptitude section Quantitative Aptitude basics: • Numbers: All that we have covered till 8th standard. • Arithmetic: All that we have learnt till 8th standard. • Geometry: All that we have learnt till 10th standard. • Algebra: All that we have learnt till 10th standard. • Modern Math (Permutation & combination, Probability, Set theory and Trigonometry etc.): All that we have learnt till class 10th standard. Note: Derivation and proofs of formulae are not of much use in solving the questions but these help in building the concepts.
Key pointers to crack Quantitative Aptitude section • Speed Matters - Practice speed maths • Regular practice, hard work and consistency will pay off. • Quant section is not a test of one’s intelligence. • Understanding the statement and interpretation correctly is the most critical part. • Visualization of a question can help a lot in solving the question. • No prior knowledge is required to crack many of the questions. • With a net score of 50% marks, you can be in the top 1% of CAT population !!
Key pointers to crack Quantitative Aptitude section Alternative Methods: • Some of the questions can be cracked • Logically • By simply eliminating the other options • By plugging the specific value

2. Each of Saral, Pranav and Jatin has a certain number of marbles in the beginning. They play a game in which every person has to double the number of marbles with every other person. In the first round, Saral doubles the number of marbles with each of Pranav and Jatin. In the second round, Pranav doubles the number of marbles with each of Saral and Jatin. Finally, in the third round, Jatin doubles the number of marbles with each of Saral and Pranav. At the end of the third round, each has 1200 marbles. Find the number of marbles with each of them in the beginning.
Approach: Start with the end Solution 2: Each of Saral, Pranav and Jatin has a certain number of marbles in the beginning. They play a game in which every person has to double the number of marbles with every other person. In the first round, Saral doubles the number of marbles with each of Pranav and Jatin. In the second round, Pranav doubles the number of marbles with each of Saral and Jatin. Finally, in the third round, Jatin doubles the number of marbles with each of Saral and Pranav. At the end of the third round, each has 1200 marbles. Find the number of marbles with each of them in the beginning.
