Most Expected Quant Questions for IBPS RRB PO Mains Exam 2025

The Quantitative Aptitude section is one of the most scoring and decisive sections of the IBPS RRB PO 2025 Mains Exam, carrying 40 questions for 50 marks to be attempted in just 30 minutes. To perform well under such time pressure, candidates must prioritize accuracy and focus on questions that are most likely to be asked. This article is aiming to help aspirants by providing a list of the most expected Quant questions for IBPS RRB PO 2025 Mains Exam, enabling candidates to practice high-probability topics and strengthen their exam-oriented preparation.

Most Expected Quantitative Questions For IBPS RRB 2025 PO Mains Exam

Based on recent exam trends and analysis of previous years’ RRB PO Mains papers, Data Interpretation (DI), Quadratic Equations, Simplification/Approximation, and Number Series are among the most expected question types for the 2025 Mains exam. But, before we learn about the expected questions candidates must check the exam pattern in the table below.

1. Data Interpretation (DI) – Highest Priority Topic

Data Interpretation is expected to dominate the Quant section, both in number of questions and difficulty level. Most DI sets in Mains are calculation-intensive and arithmetic-based rather than straightforward data reading.

Expected DI Formats:

• Pie Chart Data Interpretation
• Tabular Data Interpretation
• Graphical DI (Bar Graph / Line Graph)
• Caselet or Descriptive DI

Arithmetic-Based DI Topics Likely to Be Asked:

• Probability
• Work and Time
• Mixture and Allegation
• Speed, Time and Distance
• Profit and Loss

Apart from arithmetic-based DI, questions may also be framed from:

• Average
• Percentage
• Ratio and Proportion

Tip: Attempt DI sets only if calculations look manageable. Leaving one tough DI set can save valuable time for scoring areas.

2. Quadratic Equation Questions – Sure-Shot Scoring Area

Quadratic equations continue to be a highly expected and scoring topic in the IBPS RRB PO 2025 Mains exam. Questions are usually comparison-based and can be solved quickly with practice.

Expected Question Pattern:

• Solve two quadratic equations
• Compare roots using symbols: <, =, ≥, ≤, or No relation

Why Important:

• Less time-consuming
• High accuracy
• Ideal for maximizing marks quickly

3. Simplification & Approximation – Accuracy-Driven Questions

Simplification and approximation questions are frequently asked in Mains and test a candidate’s calculation speed and number sense.

Expected Areas:

• BODMAS-based expressions
• Approximation of large values
• Use of fractions, squares, and percentages

Strategy: Attempt only those questions where approximation is clearly possible. Avoid over-calculating.

4. Number Series – Pattern Recognition Matters

Number series questions are another most expected component of the Quant section. These questions test logical thinking and quick pattern identification.

Expected Types:

• Missing Number Series
• Wrong Number Series
• Mixed Arithmetic Series
• Commonly used concepts include:
• Squares and cubes
• Difference and second difference
• Multiplication/division patterns

Tip: Do not spend more than 30–40 seconds per series question.

Smart Attempt Strategy for Quant Section

• Do not aim to attempt all 40 questions
• Focus on high-accuracy topics like Quadratic Equations, Simplification/Approximation and Number Series
• Choose DI sets selectively
• Maintain calculation accuracy over speed
• Avoid guesswork due to negative marking

A safe and effective attempt range is 28–32 questions with high accuracy, which can fetch a strong score in Quant.

Candidates who prioritize accuracy over attempts, practice calculation-heavy DI, and strengthen their basics in arithmetic topics will have a clear edge in the exam
