TNPSC Group 4 Aptitude & Mental Ability Syllabus

The TNPSC Group 4 Exam Syllabus covers various mathematical concepts essential for problem-solving, such as simplification, percentages, ratio and proportion, interest calculations, geometry, and logical reasoning. This syllabus aims to evaluate candidates’ mathematical and analytical skills for the Group 4 examination conducted by the Tamil Nadu Public Service Commission.

1. Simplification – Candidates must demonstrate the ability to simplify complex mathematical expressions using BODMAS rules, factorization, decimals, fractions, squares, cubes, and exponents.
2. Percentage – Candidates should have a strong conceptual understanding of percentages and the capability to solve problems involving profit/loss, simple interest, compound interest, and direct proportion.
3. HCF – Finding the highest common factor for a set of numbers requires identifying the largest factor shared between the numbers through prime factorization.
4. LCM – Determining the lowest common multiple involves finding the smallest multiple that two or more numbers can be divided by through analyzing their prime factors.
5. Ratio and Proportion – Grasping direct and inverse proportion, unitary method, and part-whole relationships are needed to solve ratio and proportion word problems.
6. Simple and Compound Interest – Conceptual clarity about principal amount, interest rate, and time period is essential to accurately calculate interest and perform related calculations.
7. Area and Volume – Formulas for squares, rectangles, triangles, circles, cubes, cylinders, and other shapes must be applied accurately to find area and volume.
8. Time and Work – Analytical skills are required to comprehend time and work problems and compute time taken when work rates are given.
9. Logical Reasoning – Strong analytical abilities, problem-solving skills, and out-of-the-box thinking are essential to solve statements, assumptions, conclusions, inferences, and interpret data accurately.
10. Puzzles – Critical thinking and creative problem-solving are needed to decipher patterns, decode messages, and interpret puzzles.
11. Visual Reasoning – Test takers must utilize visual clues, patterns, and logical reasoning to derive conclusions from images, figures, signs and symbols accurately.
12. Alpha Numeric Reasoning – Strong reasoning ability is required to comprehend and solve problems involving alphanumeric sequences, coding and relationships between letters, numbers and symbols.
13. Number Series – Identifying patterns and understanding number relationships is crucial for continuing number series and predicting missing or next terms.
