Goa TET – Reasoning Ability
Topic: Puzzles
What are puzzles?
Think of puzzles as little brain‑games that give you a set of facts and ask you to find the missing piece—just like a detective solving a mystery.
1. Why Puzzles Matter
| Reason | Everyday Analogy |
|---|---|
| Logical thinking | Figuring out which seat is best for a family movie night. |
| Attention to detail | Spotting the wrong shoe in a stack of shoes. |
| Speed & accuracy | Completing a jigsaw puzzle before the movie starts. |
2. Types of Puzzles You’ll See
| Puzzle Type | Quick Description | Sample Question |
|---|---|---|
| Logic (Grid) Puzzles | A little table with clues; you fill in the blanks. | “Three friends A, B, C are sitting on a bench. A sits next to B but not on the left. Who sits in the middle?” |
| Sequence Puzzles | Numbers or letters that follow a rule. | “4, 6, 9, 13, … What comes next?” |
| Spatial/Visual Puzzles | Shapes, pictures, or arrangements that need to be matched. | “If you rotate the shape 90° clockwise, what will it look like?” |
| Sudoku‑style | Fill a grid so that each row, column, and block has all numbers. | “Complete the 4×4 Sudoku below.” |
Tip: In Goa TET, most puzzles are logic or sequence based. Spatial puzzles appear less often.
3. How to Attack a Puzzle – A Step‑by‑Step Guide
-
Read the whole problem once.
Imagine you’re planning a party: you first read the invitation before deciding on the menu. -
Identify the facts.
Write them down on a piece of paper or in a small table. -
Look for constraints.
Constraints are the “rules” in the puzzle—like “no two friends sit together.” -
Eliminate impossibilities.
Just as you’d rule out a dish that you’re allergic to, cross out options that break a rule. -
Fill in what you’re sure of.
Keep building until only one option remains for each slot. -
Double‑check.
Give yourself a quick mental check: “Does this fit all the clues?”
4. Tiny Example – A Simple Logic Puzzle
Problem
Three friends, Ravi, Meena, and Sunil, are buying tickets for a concert.
- Ravi buys a front row ticket.
- Meena does not buy a back row ticket.
- The one who buys a mid row ticket is not Sunil.
Question: Who buys the back row ticket?
Solution
| Friend | Ticket |
|---|---|
| Ravi | Front |
| Meena | Not Back |
| Sunil | Not Mid |
- From 2: Meena is not back.
- From 3: Sunil is not mid.
- That leaves Meena → Front (but Ravi already has Front).
- Thus Meena must have Mid.
- Therefore Sunil has Back.
Answer: Sunil buys the back row ticket.
Why it works – By eliminating the impossible choices step by step, only one option fits all clues.
5. Quick Strategies for Each Puzzle Type
| Puzzle | Strategy |
|---|---|
| Logic | Use a grid or table. Mark “✓” for true, “✗” for false. |
| Sequence | Look for a pattern: add 2, add 3, add 4… or multiply, alternate. |
| Spatial | Draw or imagine the shape. Rotate or flip mentally before drawing. |
| Sudoku | Work row‑by‑row; use the “only one place” rule. |
6. Practice Tips
-
Start small.
Solve 5 simple puzzles each day. -
Time yourself.
Set a timer of 2–3 minutes per puzzle to build speed. -
Check your work.
After solving, quickly review the clues to catch mistakes. -
Use online resources.
Websites like “Logic Puzzles” or “Sudoku” offer free daily puzzles. -
Track mistakes.
Keep a small notebook: write the puzzle, your answer, and why you made an error.
7. Sample Practice Question (for Goa TET)
Question
In a row of 5 seats, people A, B, C, D, and E sit.
- A sits immediately to the left of B.
- C sits somewhere to the right of D.
- E does not sit at either end.
Find the seating order from left to right.
Quick Solution
- A left of B → A‑B is a pair.
- E not at ends → E can be seat 2, 3, or 4.
- C right of D → D must be left of C.
Try A‑B at seats
