Symbol Based Problems – Logical Reasoning – MBA CUET PG – Notes & Practice Questions

Mathematical operation questions involve the basic arithmetic operators:

• Addition (+)

• Subtraction (–)

• Multiplication (×)

• Division (÷)

Sometimes, operators like greater than (>), less than (<), and equal to (=) are also used.

In these questions, special symbols or letters may replace the usual operators, and you must identify the correct operation in order to solve the equation.

Types of Questions

There are two types of mathematical-operation problems:

1. Symbol-Based Equations

Here, different symbols or letters represent different mathematical operations.
You must decode the meaning of each symbol and then solve the expression logically.

Example:

100 M 25 G 2 K 12

Suppose:

• M represents division (÷)

• G represents multiplication (×)

• K represents addition (+)

Then the expression is solved by replacing symbols with their respective operations.

2. Equation Checking

In this type, four equations are given.
You must check which one of them is mathematically correct by applying standard rules.

Important Rules to Remember

While solving these problems, always follow:

BODMAS Rule

• B – Brackets

• O – Of

• D – Division

• M – Multiplication

• A – Addition

• S – Subtraction

This rule tells you which operations to perform first in any mathematical expression.

Practice Questions
