📘 Introduction
Logical reasoning is one of the most important sections in OSSSC exams like RI, ARI, Amin, and Forest Guard. It tests your ability to analyze patterns, relationships, and logical thinking. Common topics include analogy, classification, coding-decoding, number series, and seating arrangement.
Regular practice of MCQs helps improve speed and accuracy. This quiz is designed with simple explanations so that you can understand the logic behind each question instead of just memorizing answers. With consistent practice, reasoning can become one of your strongest scoring sections.

- Series = sequence pattern
- Practice improves speed
- Easy scoring section
📌 Conclusion
Reasoning is one of the easiest sections to score in OSSSC exams if you practice regularly. Focus on understanding patterns rather than memorizing answers. Start with basic topics like analogy and series, then move to advanced topics like puzzles and seating arrangement. Consistent practice will help you solve questions quickly and accurately during the exam.
OSSSC Reasoning – 100 MCQs (My Real Study Notes for RI, ARI, Amin, Forest Guard, ICDS, CGL)
So, I started preparing Reasoning for OSSSC exams and at first I thought — “This is easy, no theory, just logic.”
But when I actually solved MCQs… I was like, “Why am I getting this wrong?” 😅
Questions looked simple, but I made silly mistakes. Sometimes I understood the concept, but still marked the wrong option.
Then I realized one thing:
Reasoning is not tough, but it needs practice + patience.
So here I’m sharing how I improved, in a simple way. Like I’d explain to my friend.
What is Reasoning (Simple Idea)
Reasoning is basically checking how you think.
Not what you memorized, but how you solve problems.
There are two main types:
- Verbal Reasoning
- Non-Verbal Reasoning
At first, I didn’t know the difference. But now it’s clear.
1. Verbal Reasoning
This part uses words and logic.
Important topics:
- Analogy
- Coding-Decoding
- Blood Relation
- Direction Sense
- Syllogism
My experience:
When I first tried coding-decoding, I got confused.
But then I started looking for patterns instead of guessing.
Example:
If CAT = DBU
Then DOG = ?
Just shift letters +1 → EPH
My trick:
Don’t panic. Just check pattern step by step.
2. Blood Relation
This topic confused me a lot earlier 😅
My method:
I draw small diagram.
Example:
“Ram is father of Shyam, Shyam is brother of Mohan”
I draw it like a tree.
Then answer becomes easy.
Tip:
Never solve in mind. Always draw.
3. Direction Sense
This is easy if you imagine movement.
Example:
If a person goes north, then right, then left…
I imagine myself walking.
My trick:
Use hand or rough paper to track direction.
4. Syllogism
This topic is tricky.
Example:
All cats are animals
Some animals are dogs
Conclusion?
My learning:
Don’t assume extra information.
Only use given statements.
5. Non-Verbal Reasoning
This part is about images and patterns.
Topics include:
- Series
- Mirror image
- Figure completion
- Odd figure
My experience:
At first, I guessed answers.
But then I started observing patterns carefully.
Example:
In figure series, check:
- Shape
- Rotation
- Size
Tip:
Look for small changes.
How I Practice MCQs
Earlier, I solved random questions.
Now I follow this:
- Choose one topic
- Understand pattern
- Solve 20–30 MCQs
- Check mistakes
- Revise
This improved my speed.
Sample MCQs
1. Find next: 2, 4, 6, 8, ?
Answer: 10
2. Odd one out: Dog, Cat, Tiger, Table
Answer: Table
3. If A=1, B=2, then BAT=?
Answer: 2+1+20 = 23
4. Ram is brother of Shyam. Shyam is father of Mohan. Ram is?
Answer: Uncle
5. All apples are fruits. Some fruits are mangoes. Conclusion?
Answer: Cannot say apples are mangoes
Mistakes I Made
1. Guessing answers
Didn’t check pattern properly.
2. Solving in mind
Got confused in blood relation.
3. Rushing
Made silly mistakes.
One Small Insight
After practicing daily, I noticed something.
My thinking speed improved automatically.
At first:
- I took more time
Now:
- Faster + more accurate
One Relatable Example
Sometimes I see a question and feel: “I know this…”
But still choose wrong option.
Now I pause for 2 seconds and recheck.
It helps a lot.
My Personal Tips
1. Practice daily
Reasoning needs practice.
2. Don’t fear tough questions
Start easy, then improve.
3. Use rough work
Very important.
4. Stay calm
Don’t panic.
Final Thoughts
Reasoning for OSSSC exams is scoring.
No need to memorize anything.
Just understand patterns and practice.
Just remember:
- Practice regularly
- Improve speed
- Maintain accuracy
Even 1 hour daily is enough.
MCQ Practice Rules
- Read question carefully
- Don’t assume
- Use pen and paper
- Skip tough questions
- Analyze mistakes
