SSC CHSL 2027: Simplification Questions Using BODMAS

Simplification is an important topic in quantitative aptitude for SSC CHSL 2027 preparation. The BODMAS rule helps you solve mathematical expressions in the correct order and avoid calculation mistakes. Revise the rule, follow the solved examples and practise the MCQs below.

1. What Is the BODMAS Rule?

BODMAS is a rule that explains the order in which mathematical operations should be performed.

Important: Division and multiplication have equal priority, as do addition and subtraction. When operations have equal priority, solve from left to right.

2. Solved Examples Using BODMAS

Example 1: Solve 12 + 6 × 2

First, multiply: 6 × 2 = 12

Then add: 12 + 12 = 24

Answer: 24

Example 2: Solve (18 − 6) ÷ 3

First, solve the bracket: 18 − 6 = 12

Then divide: 12 ÷ 3 = 4

Answer: 4

Example 3: Solve 20 ÷ 5 × 2

Division and multiplication have equal priority, so solve from left to right.

20 ÷ 5 = 4

4 × 2 = 8

Answer: 8

Example 4: Solve 3 + 2² × 4

First, calculate the power: 2² = 4

Then multiply: 4 × 4 = 16

Finally, add: 3 + 16 = 19

Answer: 19

Answer: B. 11

4. Common BODMAS Mistakes to Avoid

• Do not perform addition before multiplication when multiplication has higher priority.
• Always solve brackets before operations outside them.
• Calculate powers and roots before division, multiplication, addition or subtraction.
• Perform multiplication and division from left to right when they appear at the same level.
• Recheck each calculation instead of solving the entire expression mentally in one step.

5. Frequently Asked Questions

Conclusion

For SSC CHSL 2027 simplification questions, remember the correct order of operations and practise calculations regularly. Pay special attention to brackets, powers, and left-to-right evaluation of operations with equal priority.
