 *************************************************************************

In this session, Mr. Anshu Verma, Expert Faculty at Drishti IAS, covers two of the most important topics in Quantitative Aptitude—Average and Ratio—which are highly relevant for CSAT and UPSC Prelims 2026.
The class begins with the basic concepts and formulas of Average, including questions based on natural numbers, impact of adding or subtracting equal values, wrong data-based questions, and problems involving addition or removal of a group (weighted average).
Further, the session explores Ratio in detail, including its fundamental concepts, simplification, proportion, and applications in various topics such as age problems, partnership, mixture and alligation, income-expenditure, and data interpretation. Previous Year Questions (PYQs) are also discussed with both logical and conventional approaches to strengthen conceptual clarity.
This session is designed to help aspirants build a strong foundation in maths and improve their problem-solving skills for exams.
