CAT 2025 Slot 2 Quant Marathon | Complete QA Solutions

In this session, Rajesh Sir solves the entire Quantitative Aptitude section of CAT 2025 Slot 2, discussing each question the way it should be approached in the actual exam. The focus is not on shortcuts or speed tricks, but on understanding how CAT frames Quant questions and how a student should think under time pressure.

This Quant Marathon is especially useful if you are analysing your CAT 2025 attempt or if you are preparing for CAT 2026 using previous year questions. The questions in this slot cover a good mix of Arithmetic, Algebra and other core CAT topics, making this video a solid reference for anyone serious about CAT Quant preparation.

As Rajesh Sir works through the paper, he also explains which questions were worth attempting, which ones could have been skipped, and how small decisions inside the exam can make a big difference to your final score. Watching the full solve will help you develop better judgement, not just better speed.

You can use the timestamps provided to jump directly to any question. It is strongly recommended that you pause the video and try solving each question on your own before watching the explanation.
