Simplification is one of the most scoring topics of the quant section in RRB PO Exam. In  Prelims, simplification contributes to 8-10 marks. It is a topic that requires fast calculation skills and a strong hold on concepts such as percentage-fraction conversion, as they are frequently used topics. To make a strong hold over this concept, you need to do a lot of practice. To help you with the same, we have come up with a PDF that contains 50+ exam-level simplification questions for you to practice and ace the exam.  <\/p>\n\n\n\n

Concepts used to Solve Simplification Questions <\/h2>\n\n\n\n

In this section, we are providing a list of concepts that you need while doing calculations. Using these concepts while solving the questions enhances the chances of accuracy and speed as well. The topics are listed below-<\/p>\n\n\n\n

BODMAS Rule<\/strong> (Brackets, Order, Division, Multiplication, Addition, Subtraction)
It defines the correct sequence to perform mathematical operations. Always solve expressions step by step, following this order to get accurate results.
<\/p>\n\n\n\n

Approximation-based problems<\/strong><\/p>\n\n\n\n

These questions require rounding off numbers to the nearest value for faster calculation. The goal is to find a value close enough to the exact answer within reasonable accuracy.
<\/p>\n\n\n\n

Fractions and Decimals<\/strong><\/p>\n\n\n\n

Fractions represent parts of a whole, while decimals express the same in base-10 form. Converting between them helps simplify arithmetic operations quickly.
<\/p>\n\n\n\n

Square and Cube Roots<\/strong><\/p>\n\n\n\n

These help in simplifying numbers raised to powers. Memorising square and cube values up to at least 30 and 20, respectively, boosts speed in calculations.
<\/p>\n\n\n\n

Percentage-based simplifications<\/strong><\/p>\n\n\n\n

These involve converting percentages into fractional or decimal forms for quick solving. They often appear in profit-loss, interest, and ratio-related questions.
<\/p>\n\n\n\n

Surds and Indices<\/strong><\/p>\n\n\n\n

Surds deal with irrational roots (like \u221a2, \u221a3), while indices represent powers or exponents. Understanding their laws helps simplify expressions involving roots and powers efficiently.<\/p>\n\n\n\n

Common Types of Simplification Questions<\/h2>\n\n\n\n

In this section, we have discussed the common types of simplification questions that have been asked in the examination. <\/p>\n\n\n\n

    \n
  1. Pure BODMAS Type:<\/strong>
    <\/strong> Example: 15 + {12 \u00d7 (8 \u2013 6)} \u00f7 3
    \u2192 15 + (12 \u00d7 2) \u00f7 3 = 15 + 24 \u00f7 3 = 23
    <\/strong><\/li>\n\n\n\n
  2. Mixed Fractions:<\/strong>
    <\/strong> Example: \u00be of 120 + \u2156 of 50
    \u2192 90 + 20 = 110<\/strong>
    <\/strong><\/li>\n\n\n\n
  3. Square\/Cube Roots:<\/strong>
    <\/strong> Example: \u221a144 + \u221b27 = 12 + 3 = 15
    <\/strong><\/li>\n\n\n\n
  4. Percentage-based:<\/strong>
    <\/strong> Example: 20% of 240 + 25% of 320 = 48 + 80 = 128
    <\/li>\n\n\n\n
  5. Approximation-based:<\/strong>
    <\/strong> Example: 49.8 \u00d7 2.02 \u2248 50 \u00d7 2 = 100<\/li>\n<\/ol>\n\n\n\n

    Approach to Solve Simplification Questions in RRB PO Exam 2025<\/strong><\/h3>\n\n\n\n

    The way or approach you use while solving the questions is very important, as it decides whether you\u2019ll be able to solve the questions and get accurate results or not.  <\/p>\n\n\n\n

    1. Understand the BODMAS Rule<\/strong><\/h4>\n\n\n\n

    Always perform operations in the correct order:
    Brackets \u2192 Orders \u2192 Division \u2192 Multiplication \u2192 Addition \u2192 Subtraction<\/strong>.
    Ignoring this sequence leads to calculation errors.<\/p>\n\n\n\n

    2. Learn Square and Cube Values<\/strong><\/h4>\n\n\n\n

    Memorise squares up to 30 and cubes up to 20. It helps simplify large expressions faster without using rough work.<\/p>\n\n\n\n

    3. Master Fractions and Percentages<\/strong><\/h4>\n\n\n\n

    Keep common conversions handy:<\/p>\n\n\n\n
