Top Tips to Solve Syllogism Questions Fast

Syllogism is an important topic in the Reasoning Ability section of the RBI Grade B Phase 1 exam. This topic typically carries 3–5 marks and is a regular feature in the exam every year. It tests your ability to draw logical conclusions based on given statements. These questions may seem easy, but they often include twisty statements. They have confusing logic that is designed to confuse you, if you’re not careful. Therefore, mastering Syllogism is essential if you want to maximize your overall score in the Reasoning section. And the good part is that you can solve these questions quickly and accurately. But only with the right techniques and regular practice. In this blog, we’ll share simple and smart tips to help you improve your speed and accuracy in Syllogism. Plus, you’ll also find sample questions with solutions to fine-tune your preparation.

Best Tricks to Solve Syllogism Questions Quickly

Syllogism tests a candidate’s ability to logically deduce conclusions from given statements. Syllogism questions look easy at first glance. But they can be tricky if not solved in the right way. So, many candidates get confused between “some”, “all”, “no” or “some not” type statements. That’s where practice and strategy come in. Here are the best tips that, if you follow, can help you master the strategy to solve all types of syllogism questions smartly:

1. Understand the Keywords Clearly

Syllogism questions depend on logic. And logic depends on understanding each keyword properly. Don’t mix up “some”, “some not”, “all” and “no”.

Here’s what to keep in mind:

• “All A are B” means every A is inside B.
• “Some A are B” means at least one A is B.
• “No A is B” means A and B are completely separate.
• “Some A are not B” means at least one A is outside B.
• Knowing the exact meaning avoids silly mistakes.

2. Use Venn Diagrams to Visualize

Never try to solve Syllogism questions in your head. The best way is to draw Venn diagrams and see the relationships visually.

Here are some tips:

• Use circles to represent each group or term.
• Overlap only when required.
• Don’t force overlap if not mentioned.
• Try drawing all possible diagrams if needed.
• This method works best with “possibility” type questions.

3. Practice Reverse Checking for Conclusions

Sometimes, the conclusion seems true at first, but it’s not always valid. Try checking the conclusion with all possible diagrams.

Let’s see how:

• If a conclusion is true in all possible cases, it’s valid.
• If even one diagram shows it false, it’s invalid.
• For possibility questions, check if it’s possible, not definite.
• This technique avoids getting tricked by half-true statements.

4. Focus on Common Patterns and Shortcuts

Most questions follow a few standard patterns. Learn those and solve questions faster.

Try this:

• “All + All = All”
• “All + No = No”
• “Some + All = No Conclusion”
• Learn these patterns by heart.
• Use them to eliminate wrong options quickly.

5. Practice Timed Sets Regularly

Speed is key in the exam. Build your habit of solving each question in under 1 minute.

Here’s how:

• Use a timer during practice.
• Track your accuracy and timing.
• Practice both basic and tricky cases.
• Take mock tests to build real exam stamina.

Sample Syllogism Questions for Practice

Given below are some of the most important questions with solutions that will help you better understand syllogism questions and how to face them:

Question 1: In the question below some statements are given two conclusions followed by some statements. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read the conclusions and then decide which of the following statement is true for given conclusions.

Conclusions:

I. No Rainy are Summer

II. Some Summer being Autumn is a possibility

Statements:

A) No Spring are Rainy. 100% Rainy are Winter. 100% Autumn are Winter. No Winter are Summer.

B) All Rainy are Winter. No Rainy are Spring. A few Summer are Autumn. All Autumn are Winter.

C) Some Winter are Rainy. Only Winter are Summer. Only a few Rainy are Autumn. All Spring are Autumn.

D) Only Winter are Rainy. Only a few Autumn are Winter. No Winter are Summer. Only a few Summer are Spring.

E) None of the above

Solution:

Now, by drawing the Venn diagram we get:

Statement (a):

I. No Rainy are Summer follows.

II. Some Summer being Autumn is a possibility doesn’t follow.

Statement (b):

I. No Rainy are Summer doesn’t follow.

II. Some Summer being Autumn is a possibility doesn’t follow.

Statement (c):

I. No Rainy are Summer follows.

II. Some Summer being Autumn is a possibility doesn’t follow.

Statement (d):

I. No Rainy are Summer follows.

II. Some Summer being Autumn is a possibility follow.

Statement (d) will make both the conclusions definitely follow.

Hence, option d.

Question 2: In the question below there are three conclusions followed by four statements in the options. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given statements are true disregarding the commonly known facts.

Conclusions:

No round is square.

Some square are not parallel.

Some circle are round.

Statements:

A) Some circle are square. Some rectangle are square. Some rectangle are parallel. Some circle are round.

B) All circle are round. All circle are square. Some rectangle are square. All rectangle are parallel.

C) All circle are square. Some circle are round. Some rectangle are square. No rectangle is parallel.

D) Only circle are round. Some circle are square. Some rectangle are square. No rectangle is parallel.

E) None of the above

Solution:

The following figures can be formed:

From the figures, only the statements given in option (d) are true.

Hence, option d.

Question 3: In the question below there are three conclusions followed by four statements in the options. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given statements are true, disregarding the commonly known facts.

Conclusions:

Some five are not nine.

Some seven are eight.

Some six are not eight.

Statements:

A) No nine is eight. Some eight are five. Some five are seven. All six are nine.

B) Some six are nine. No nine is eight. Some eight are five. All five are seven.

C) Some six are nine. Some nine are eight. Some eight are five. Some five are seven.

D) Some five are seven. Some six are nine. All nine are eight. Some eight are five.

E) None of the above

Solution:

Following figures can be formed:

From the figures, only the statements given in option (b) are true.

Hence, option b.

Question 4: In the given question, two columns are given such that column I has three sets of statements while column II has three sets of conclusions. You have to assume the given statement to be true even if they seem to be at variance from commonly known facts. Match the conclusions S, T and U which will logically follow the statement P, Q and R disregarding the commonly known facts.

(A statement is said to be followed if both the conclusions given against the statement S, T and U are true according to the statements P, Q and R)

Column I	Column II
P. Only City are Metro. No City are Bus. All Train are Bus.	S. All Train can be Metro. Some City are not Metro is a possibility.
Q. Only a few Metro are City. All City are Bus. No Bus are Train.	T. Some Metro are Train is a possibility. Some Bus are Train is a possibility.
R. Only a few Bus are City. Only a few City is Train. Only a few Metro areTrain.	U. Some Train can never be City. No Bus are Metro.

A) PT and RU

B) RT and RS

C) RS and PU

D) RT and TU

E) PU and QU

Solution:

P.) Only City are Metro. No City are Bus. All Train are Bus.

So, following figure can be formed from the statement:

S. All Train can be Metro is definitely false. Some City are not Metro is a possibility is definitely false.

T. Some Metro are Train is a possibility is definitely false. Some Bus are Train is a possibility is definitely false.

U. Some Train can never be City is definitely true. No Bus are Metro is definitely true.

So, U follows from P.

Q). Only a few Metro are City. All City are Bus. No Bus are Train.

Following figure can be formed from the statements:

S. All Train can be Metro is definitely true. Some City are not Metro is a possibility is not definitely true.

T. Some Metro are Train is a possibility is definitely true. Some Bus are Train is a possibility is definitely false.

U. Some Train can never be City is definitely true. No Bus are Metro is definitely false.

So, U doesn’t follow from Q.

R.) Only a few Bus are City. Only a few City is Train. Only a few Metro are Train.

Following figure can be formed from the statements:

S.All Train can be Metro is definitely true. Some City are not Metro is a possibility is definitely true.

T. Some Metro are Train is a possibility is definitely false. Some Bus are Train is a possibility is definitely true.

U. Some Train can never be City is definitely false. No Bus are Metro is definitely false.

So, S follows from R.

Hence, option c.

Question 5: In the question below some statements are given two conclusions followed by some statements. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read the conclusions and then decide which of the following statement is true for given conclusions.

Conclusions:

I. No Friends are Love

II. Some Hate are not Care

Statements:

A) All Love are Hate. Only a few Care are Hate. No Hate are Affection. All Friends are Affection.

B) All Love are Hate. No Friends are Affection. Some Affection are Hate. Only Hate are Care.

C) All Hate are Friends. Some Hate are Care. Only Care are Affection. No Love are Care.

D) All Friends are Hate. Every Hate are Affection. Only Affection are Love. No Affection are Care.

E) None of the above

Solution:

Now, by drawing the Venn diagram we get:

Statement (a):

I. No Friends are Love follows.

II. Some Hate are not Care doesn’t follow.

Statement (b):

I. No Friends are Love definitely doesn’t follow.

II. Some Hate are not Care follows.

Statement (c):

I. No Friends are Love doesn’t follow.

II. Some Hate are not Care doesn’t follow.

Statement (d):

I. No Friends are Love follows.

II. Some Hate are not Care follows.

Statement (d) will make both the conclusions definitely follow.

Hence, option d.
