What Is Approximation in SBI PO Exam?
Approximation Questions SBI PO 2026 require you to find a value that is close to the actual answer without doing the complete calculation. Instead of spending time calculating exact values, you use nearby numbers that make the calculation easier. Approximation is especially useful when the answer options are far enough apart to identify the correct option quickly. An example of an Approximation with questions and answers in PDF format is provided below. Download now.
For example:
49.8 ≈ 50
19.9 ≈ 20
398.7 ≈ 400
The main idea is simple: Round smartly, calculate quickly, and select the closest option.
Practice Set of Approximation Questions SBI PO 2026 : Free Quiz
Here is a list of 10 approximation questions SBI PO 2026 for students reference. Practice these questions with a timer to improve your calculation speed, accuracy, and confidence for the SBI PO Quantitative Aptitude section.
Q1. What approximate value should replace the question mark? 79.8 + 39.9 × 5.1 = ?
Explanation: 79.8≈80, 39.9≈40, 5.1≈5. So 80 + 40×5 = 280.
Q2. What approximate value should replace the question mark? (599.2 ÷ 19.9) + 49.8 = ?
Explanation: 599.2≈600, 19.9≈20, 49.8≈50. So 600÷20 + 50 = 80.
Q3. What approximate value should replace the question mark? 24.9% of 399.5 + 19.8 = ?
Explanation: 24.9%≈25%, 399.5≈400, 19.8≈20. So 25% of 400 + 20 = 120.
Q4. What approximate value should replace the question mark? √625 + 39.8 × 4.9 = ?
Explanation: √625=25, 39.8≈40, 4.9≈5. So 25 + 40×5 = 225. The closest option is 220, Option C.
Q5. What approximate value should replace the question mark? 799.6 ÷ 40.2 + 29.7 × 3.1 = ?
Explanation: 800÷40 + 30×3 ≈ 20 + 90 = 110. The exact value is about 111.89, so 120 is the closest option.
Q6. What approximate value should replace the question mark? (49.8 × 20.2) ÷ 10.1 = ?
Explanation: 50×20÷10 ≈ 100.
Q7. What approximate value should replace the question mark? 119.8 + 24.9% of 200.2 − 39.7 = ?
Explanation: 120 + 25% of 200 − 40 = 120 + 50 − 40 = 130.
Q8. What approximate value should replace the question mark? (299.8 ÷ 14.9) + (199.6 ÷ 10.1) = ?
Explanation: 300÷15 + 200÷10 ≈ 20 + 20 = 40.
Q9. What approximate value should replace the question mark? 39.8 × 24.9 + 100.2 ÷ 5.1 = ?
Explanation: 40×25 + 100÷5 ≈ 1000 + 20 = 1020. The exact value is about 1010.71, so 1000 is the closest option.
Q10. What approximate value should replace the question mark? (699.5 ÷ 35.1) + 49.8 × 2.1 = ?
Explanation: 700÷35 + 50×2 ≈ 20 + 100 = 120.

SBI PO 2026 Quantitative Aptitude: Where Does Approximation Fit?
The Approximation Questions SBI PO 2026 topic can help candidates improve calculation speed and make better use of the limited time available in the Quant section.
The SBI PO Quantitative Aptitude section tests calculation ability, number sense, arithmetic concepts, data interpretation, and other numerical topics. The current SBI PO syllabus includes Simplification and Approximation along with Number Series, Data Interpretation, Quadratic Equations, Arithmetic, and other Quant topics.
The SBI PO Quant strategy also identifies Approximation, Quadratic Equations, and Number Series among the more scoring areas where speed calculation can make a difference.
Approximation Questions SBI PO 2026: Important Question Types
You can expect Approximation Questions SBI PO 2026 in different forms. The numbers may look difficult, but the calculation often becomes easy after proper rounding.
The most common types include:
- Addition and subtraction
- Multiplication
- Division
- Percentage calculations
- Square roots
- Fractions
- Mixed arithmetic expressions
- Missing-value questions
- Decimal calculations
- Questions involving BODMAS
How to Solve Approximation Questions in SBI PO Exam Quickly?
Follow these simple steps to solve Approximation Questions SBI PO 2026 faster and avoid unnecessary calculations. The key is to round numbers wisely while keeping the final value close to the actual answer.
Use the options to your advantage and avoid exact calculations whenever approximation is sufficient.
Step 1: Look at the Answer Options
Before calculating, check how far apart the options are. If the options are extreme, you do not need an extremely accurate calculation. A rough estimate will be enough.
Step 2: Round the Numbers
Convert complicated numbers into nearby easy numbers. Do not round blindly. Choose values that make the calculation simple while keeping the estimate close.
For example:
- 79.8 → 80
- 49.2 → 50
- 19.7 → 20
- 299.6 → 300
- 998.5 → 1000
Step 3: Follow BODMAS
Following BODMAS helps you avoid calculation mistakes and reach the approximate answer faster. For expressions containing different operations, follow the correct order:
B – Brackets
O – Orders
D – Division
M – Multiplication
A – Addition
S – Subtraction
Step 4: Compare the Estimate With the Options
Once you get an approximate value, check which option is closest. Do not continue calculating if the answer is already clear.
Step 5: Avoid Over-Approximation
Approximation should save time, not create mistakes. But if the options are very close to one another, you may need a more careful estimate.
How to Prepare Approximation for SBI PO 2026?
Approximation is mainly a speed and accuracy topic. You do not need to spend hours studying it. Instead, practise a small number of questions every day. Regular practice of Approximation Questions SBI PO 2026 can help you become faster at rounding numbers and choosing the correct option under time pressure.
Practise Mental Calculation
The faster these calculations become, the easier approximation questions will feel. Work on:
- Tables
- Squares
- Cubes
- Fraction-to-percentage conversions
- Percentage calculations
- Multiplication shortcuts
- Division shortcuts
Solve Questions With a Timer
Start with 10 questions. Give yourself around 5–7 minutes. Once your accuracy becomes strong, gradually reduce the time. The aim is not just to solve problems quickly but also correctly.
Analyse Your Mistakes
Maintain a small calculation mistake notebook and revise it regularly. After every practice set, check:
- Did I round the numbers correctly?
- Did I follow BODMAS?
- Did I choose the closest option?
- Did I spend too much time on one question?
- Did I make a calculation mistake?
Practise Through Mock Tests
Topic practice should eventually be combined with sectional and full-length tests. PracticeMock’s recent SBI PO preparation resources recommend topic-wise practice, previous-year questions, sectional tests, and mock-test analysis as part of preparation. You can also use the SBI PO Free Mock Test to practise the topic under exam-like time pressure.
Best Strategy to Attempt Approximation Questions
Do not try to calculate everything exactly. If the options are widely separated, use a rough estimate. If the options are very close, use more accurate rounding. When you see an Approximation Questions SBI PO 2026 question in the exam, follow this simple process:
Look at options → Round numbers → Follow BODMAS → Calculate → Compare → Move on
When Should You Skip an SBI PO Approximation Question?
Remember, approximation is supposed to save time, not consume it. Skip or return to the question if:
- The options are extremely close.
- The calculation becomes longer than expected.
- You are unsure how much to round.
- Your estimate does not match any option.
- You have already spent too much time.
Practice Plan for SBI PO Approximation Questions 2026
Try to solve at least 10–15 questions daily. Increase the difficulty after your accuracy improves. Regular practice of Approximation Questions SBI PO 2026 will help you improve calculation speed and handle time pressure more confidently.
