Maths

The RRB NTPC exam tests your knowledge in Mathematics as part of the CBT 1 stage. Number System: This covers topics like natural numbers, whole numbers, integers, rational numbers, irrational numbers, LCM (Least Common Multiple), HCF (the highest Common Factor), decimal representation, and basic operations like addition, subtraction, multiplication, and division.Fractions: Simple, compound, and mixed fractions.Ratio and Proportion: Understanding concepts of ratio and proportion, direct and indirect proportion, applications of ratio and proportion in solving problems.Percentage: Calculating percentages, converting fractions into percentages and vice versa, applications of percentages.Mensuration: Area, perimeter, and volume calculations for basic 2D and 3D shapes like squares, rectangles, circles, cylinders, cones, and spheres.Algebra: Basic algebraic operations, solving linear equations with one or two variables, quadratic equations.Geometry: Lines, angles, triangles, quadrilaterals, circles, their properties, theorems related to them.Trigonometry: Basic trigonometric ratios (sine, cosine, tangent), their applications in solving simple problems.Elementary Statistics: Measures of central tendency (mean, median, mode), basic concepts of probability.Time and Work: Concepts of speed, distance, time, and work, related problems.Simple and Compound Interest: Calculating simple and compound interest for a given principal, rate, and time.Profit and Loss: Concepts of cost price (CP), selling price (SP), profit, and loss, problems based on these concepts.
