How can I prepare for CAT? I am currently in 1st year B.Com.

Yes. Most CAT time, speed, distance questions can be solved faster using inverse and direct proportionality ratios

CAT frequently tests concepts based on relative speed, linear and circular races, trains passing platforms or other trains, boats and streams, and escalators.

Typically, 1 to 3 questions are asked from Time, Speed, and Distance in the Quant section of CAT exam. It is one of the high weightage topics within Arithmetic.

Some frequent traps in CAT exam are:

• Confusing the counts of original and new members in replacement vs. inclusion problems.
• Weighting by values instead of quantities or frequencies in weighted average setups.

Yes. Most CAT-level problems involving replacements, group additions, or combinations are designed to test logical shortcuts rather than heavy calculations.
