Simplification Questions for SBI Clerk Exam, Sample Practice Questions

Simplification Questions for SBI Clerk Exam: Simplification is one of the most important topics in the Quantitative Aptitude section of bank exams, including the SBI Clerk Exam. It holds a significant weightage, making it a scoring area for candidates who prepare well. With proper practice and understanding of simplification questions, candidates can easily improve their overall score.

In this article, we provide a guide to mastering simplification questions, tips for solving them efficiently, and a set of sample questions to help you prepare for the upcoming Bank Exams 2024.

Simplification Questions for SBI Clerk Exam

Simplification plays a crucial role in the Quantitative Aptitude section. Here’s why:

• Out of the 35 questions in the prelims, approximately 10-15 questions are based on simplification.
• By practicing simplification regularly, candidates can clear the cut-off for the Quantitative Aptitude section with speed and accuracy.

To help you prepare, we’ve curated some simplification questions with relatable difficulty levels. Solving these questions will strengthen your command over the topic and help you excel in the exam.

Rules for Solving Simplification Questions

To solve simplification problems effectively, candidates should follow these rules:

1. Master the Basics

Build a solid foundation by practicing the following regularly:

• Tables up to 25
• Squares up to 25
• Cubes up to 25
• Fraction-to-decimal conversions up to 25

Knowing these basics will not only increase your speed but also improve your accuracy.

2. Use the V-BODMAS Rule

Simplification questions are often solved using the V-BODMAS rule:

• V → Vinculum (Simplify values under the vinculum first).
• B → Brackets (Solve in the order: (), {}, []).
• O → Of (Handle “of” operations next).
• D → Division
• M → Multiplication
• A → Addition
• S → Subtraction

Always follow this order to avoid mistakes in multi-step calculations.

Example:

Solve 8+[15−(6÷2×3)]8 + [15 – (6 \div 2 \times 3)]8+[15−(6÷2×3)].

• Step 1: Solve division → 6÷2=36 \div 2 = 36÷2=3.
• Step 2: Solve multiplication → 3×3=93 \times 3 = 93×3=9.
• Step 3: Solve brackets → 15−9=615 – 9 = 615−9=6.
• Step 4: Add → 8+6=148 + 6 = 148+6=14.

The answer is 14.

3. Practice Daily

Consistency is key. Solve 10-20 simplification questions daily and include real-life calculations in your routine.

Practical Tip:

Use large numbers, such as cricket scores, to practice averages, additions, and subtractions. For example, find the average of 347, 289, and 411 or subtract 289 from 411. Regular mental calculations like these sharpen your problem-solving ability.

4. Learn Tricks and Develop Shortcuts

Simplification and approximation often have repetitive patterns or shortcuts. Learn these tricks from expert guidance (like) or develop your own methods to save time.

Examples of Tricks:

• Multiplying by 5: Instead of multiplying directly, divide the number by 2 and multiply by 10.
  For example, 72×5=(72÷2)×10=36×10=36072 \times 5 = (72 \div 2) \times 10 = 36 \times 10 = 36072×5=(72÷2)×10=36×10=360.
• Squaring Numbers Ending in 5: Use the shortcut (n×(n+1))+25(n \times (n + 1)) + 25(n×(n+1))+25.
  For example, 252=(2×3)+25=62525^2 = (2 \times 3) + 25 = 625252=(2×3)+25=625.

5. Observe Patterns Through Practice

The more you practice, the better you become at spotting correlations or patterns in calculations. This might help you develop personalized shortcuts to tackle specific types of questions efficiently.

Example:

For (25×36)÷18(25 × 36) ÷ 18(25×36)÷18, observe the pattern:

• Simplify 36÷18=236 ÷ 18 = 236÷18=2, so the calculation reduces to 25×2=5025 × 2 = 5025×2=50.

With regular practice, you can recognize such simplifications instantly.
