CA Foundation Maths 2026 Exam Pattern

The CA Foundation Maths 2026 exam pattern, as prescribed by the Institute of Chartered Accountants of India, is structured to assess a student’s speed, accuracy, and conceptual clarity through an objective (MCQ-based) format covering Business Mathematics, Logical Reasoning, and Statistics. As prescribed by the Institute of Chartered Accountants of India:

• Paper Name: Quantitative Aptitude (Paper 3)

• Exam Mode: Objective (MCQ-based)

• Total Marks: 100 Marks

• Duration: 2 Hours

• Total Questions: Approximately 100 MCQs

Section-wise Weightage

• Part A: Business Mathematics – 40 Marks

• Part B: Logical Reasoning – 20 Marks

• Part C: Statistics – 40 Marks

Marking Scheme

• Correct Answer: +1 Mark

• Incorrect Answer: –0.25 Mark (Negative Marking)

• Unattempted Questions: No negative marking

Key Highlights

• Focus on speed + accuracy due to MCQ format

CA Foundation Maths 2026 Chapter-wise Weightage

Based on analysis of ICAI study material, RTPs, MTPs, and past exam trends (since ICAI does not officially publish fixed weightage), the following is a verified range-based weightage distribution:

Business Mathematics (40 Marks Section)

• Time Value of Money → ~12–16 marks (Highest weightage, consistently asked) 

• Permutations, Sequence & Series, Sets/Functions → ~12–20 marks (combined conceptual area) 

• Ratio, Indices, Logarithms, Equations → ~8–12 marks 

 Insight: Time Value of Money is one of the most reliable high-weight chapters every attempt.

Logical Reasoning (20 Marks Section)

• Number Series, Coding-Decoding, Direction, Seating Arrangement → ~12–14 marks 

• Blood Relations & Syllogism → ~6–8 marks 

 Insight: Almost the entire section is predictable and scoring with practice.

Statistics (40 Marks Section)

• Measures of Central Tendency & Dispersion + Data Representation → ~18–20 marks (Highest in entire paper) 

• Probability & Theoretical Distributions → ~10–12 marks 

• Correlation & Regression → ~4–6 marks 

• Index Numbers / Time Series → ~4–6 marks

 Insight: Statistics alone can contribute 40% of the paper, making it a major scoring area.

This weightage is generic and trend-based, derived from ICAI study material, RTPs, MTPs, and previous year papers of the Institute of Chartered Accountants of India. Actual exam weightage may vary in each attempt.
