Types of Simplification Questions Asked

Simplification includes a variety of question types. Understanding the pattern helps you practice in the right direction. The common types are

Basic arithmetic operations
Addition, subtraction, multiplication, and division with large numbers.

Operations on fractions
Questions involving improper fractions and mixed fractions.

Square and cube-based operations
Square roots, cube roots, addition or subtraction of numbers involving squares and cubes.

BODMAS-based mixed expressions
Long expressions where you must apply BODMAS correctly.

Percentage-based expressions
Calculations like 45 per cent of 360 or 12.5 per cent of 640.

Approximation-based simplification
Rough calculations where exact accuracy is not required, but smart estimation is enough.

These varieties help in improving both conceptual speed and mental maths.

How to Prepare Simplification?

To prepare for simplification effectively for PNB LBO 2025, you must follow a systematic approach. Here is a simple, actionable plan.

Strengthen your basics
Revisit tables up to 20, squares up to 40, and cubes up to 20. You should also remember common fractions like 1/6, 1/8, and 1/12. This step saves invaluable time in the exam.

Master approximation
Learn to round off numbers smartly. For example

• 394 becomes 400
  
• 56.8 becomes 57
  
• 499 becomes 500
  

This skill alone reduces calculation time by half, especially in lengthy expressions.

Practice BODMAS regularly
Many students lose marks by applying the wrong order of operations. Spend some time practising mixed expressions so that you automatically apply the correct order.

Avoid long multiplication
Use distributive property tricks. For example

• 48 × 17 = 48 × (20 − 3) = 960 − 144
  

Focus on mental maths
Keeping a small 5-minute daily drill for mental addition and subtraction significantly increases speed.

Common Mistakes to Avoid while solving the Questions

Here are some common mistakes to avoid while solving the questions during preparatio as well as in the exam.  

Spending too much time on a single question
If a question seems calculation-heavy, skip immediately. The agenda is scoring fast, not solving everything.

Ignoring approximation and trying to be exact always
Some questions are designed to be solved through estimation. Trying to calculate every digit wastes time.

Not revising tables, squares, and cubes
If you rely on pen and paper for every small multiplication, your speed drops drastically.

Poor handling of decimals and fractions
A small mistake in placing the decimal point can ruin the answer. Practise converting decimals into fractions quickly.

Not practising under timed conditions
Simplification is all about speed, so you must practise within a time limit.
