FAQs on CBSE Math Basic Past Year Paper with Solutions - 2024 (Set - 2)

1. What are the most important formulas I need to memorise for CBSE Math Basic 2024 board exams?
Ans. Essential formulas include quadratic equations (ax² + bx + c = 0), surface area and volume of solids, trigonometric ratios (sin, cos, tan), arithmetic progression sum formula [Sn = n/2(2a + (n-1)d)], and circle theorems. Students should focus on probability basics, linear equation solutions, and statistics measures like mean and median. Refer to flashcards and mind maps available on EduRev to memorise these systematically with visual representations for better retention.
2. How do I solve coordinate geometry problems that appear in CBSE Math Basic past year papers?
Ans. Coordinate geometry questions test distance formula, section formula, and collinearity of points. The distance between two points (x₁, y₁) and (x₂, y₂) is √[(x₂-x₁)² + (y₂-y₁)²]. Students should practise plotting points, finding midpoints, and calculating slopes. Working through solved examples from previous year papers helps identify recurring question patterns and common approaches used in CBSE examinations.
3. What's the difference between arithmetic and geometric progressions in Class 10 Math?
Ans. Arithmetic progressions (AP) have a constant difference between consecutive terms, with sum formula Sn = n/2(2a + (n-1)d). Geometric progressions (GP) have a constant ratio, with sum formula Sn = a(rⁿ-1)/(r-1). AP appears in linear growth problems; GP in exponential growth scenarios. Past year papers frequently test both concepts together, requiring students to distinguish between them quickly during examinations.
4. Why do I keep making mistakes in trigonometry problems from CBSE past year papers?
Ans. Common trigonometry errors include confusing sin, cos, and tan ratios, misapplying complementary angle relationships, or forgetting that sin²θ + cos²θ = 1. Students often mix up identities or apply wrong formulas for different angle values. Reviewing solved past year papers reveals which trigonometric concepts appear most frequently in CBSE examinations. Systematic practice with complementary angles and standard angles (30°, 45°, 60°) prevents these mistakes.
5. How should I approach quadratic equations differently when they appear in CBSE Math Basic exams?
Ans. Quadratic equations can be solved by factorisation, completing the square, or using the quadratic formula x = [-b ± √(b²-4ac)] / 2a. CBSE past year papers test conceptual understanding through discriminant analysis (Δ = b²-4ac) to determine nature of roots without solving completely. This discriminant-based approach saves time during board exams and appears frequently in recent question sets.
