 Logical Deduction – Verbal Reasoning (Based on R.S. Aggarwal)

Logical deduction is an essential topic in competitive exams like SSC, UPSC, Banking, GATE, CAT, and other aptitude tests.

 1. What is Logical Deduction?

Logical Deduction involves drawing conclusions from given statements using logical reasoning.

Example:
All cats are animals. Some animals are dogs. Therefore, some cats are dogs.  (Incorrect Conclusion)
All apples are fruits. All fruits are healthy. Therefore, all apples are healthy.  (Correct Conclusion)

 2. Types of Logical Deduction Questions

(A) Syllogism

• Involves statements and conclusions.
• Uses Venn Diagrams for solving.

Example:
Statement: All A are B. Some B are C.
Conclusion: Some A are C. (Check using Venn Diagrams)

(B) Statement & Conclusion

• A statement is given, and you must decide which conclusion logically follows.

Example:
Statement: “Pollution is increasing in cities.”
Conclusion 1: The government should take action.
Conclusion 2: People should plant more trees.
 Both conclusions seem logical.

(C) Statement & Assumption

• You need to find hidden assumptions behind a statement.

Example:
Statement: “The company should provide free health check-ups for employees.”
Assumption: Employees’ health affects productivity. 

(D) Cause & Effect

• Identify if one statement is the cause of the other.

Example:
Statement 1: Heavy rainfall was recorded in the city.
Statement 2: Waterlogging was reported in many areas.
Cause-Effect Relation (Rain caused waterlogging).
