• How to spot patterns and shortcuts
• A worked example that you can practice in 10 minutes
• A quick revision checklist for exam day
1. Simple Explanation
Puzzles in the TET reasoning section ask you to deduce a hidden arrangement or sequence using the given clues.
They are usually presented as:
| Format | Example |
|---|---|
| Number/Letter Arrangements | “Arrange the numbers 1–6 so that the sum of the middle three is 12.” |
| Grid/Matrix Puzzles | “Five people sit in a row. Person A is to the left of B…” |
| Logic‑Riddle/Story | “If the blue car is not in the 2nd row, then the red car must be adjacent to the green one.” |
Goal: Follow the clues exactly and fill in the missing pieces in the fewest steps possible.
2. Key Points (Quick‑Reference)
| # | Point | Why It Matters |
|---|---|---|
| 1. Read all clues first | You’ll often need to keep the whole puzzle in mind; reading one at a time can mislead you. | |
| 2. Identify the “fixed” items | Things that are explicitly mentioned (e.g., “the red car is in the first row”) give you anchors. | |
| 3. Use process of elimination | Remove impossible options early; this shrinks the search space. | |
| 4. Look for “must‑be” conditions | If a clue says “X sits next to Y”, you can immediately pair them. | |
| 5. Check for contradictions | If a choice violates any earlier clue, discard it immediately. | |
| 6. Backtrack only if needed | Most puzzles resolve in a single pass. If you get stuck, re‑evaluate the last choice you made. | |
| 7. Time‑management | Give yourself 1–2 minutes per puzzle. If you’re stuck after 3 minutes, move on and return if time allows. | |
| 8. Practice pattern recognition | Many puzzles reuse the same structure; spotting it saves time. |
3. Worked Example (5‑Minute Drill)
Puzzle
Five persons (A, B, C, D, E) are seated in a row from left to right.
- A sits immediately to the right of B.
- C sits at one end.
- D sits between A and E.
- B sits somewhere to the left of C.
- E sits immediately to the left of D.
Question: What is the complete seating order from left to right?
Step‑by‑Step Solution
| Step | Reasoning | Current Partial Order |
|---|---|---|
| 1 | Clue 2 → C is at either end: C _ _ _ _ or _ _ _ _ C. | Either possibility |
| 2 | Clue 1 → A right of B: possibilities: B A _ _ _ or _ _ B A _ or _ B A _ _. | Keep options |
| 3 | Clue 4 → B left of C. Combine with step 1: If C is at the left end, B can’t be left of it, so C must be at the right end. | _ _ _ _ C |
| 4 | Clue 3 → D sits between A and E. So A and E are on either side of D. | _ _ A D E or _ E D A _ etc. |
| 5 | Clue 5 → E immediately left of D. So “E D” must be consecutive, with E left of D. | _ _ E D _ |
| 6 | Combine 4 & 5: A must be left of E (since D is between A and E). Thus A is left of E, so the order near D is A E D. | _ A E D _ |
| 7 | Place C at the right end: _ A E D C. | Remaining person to place: B. |
| 8 | Clue 1 → A is right of B → B must be left of A. Only slot left is the leftmost. | B A E D C |
Answer: B – A – E – D – C
4. Quick Revision Summary
| Topic | Revision Tip |
|---|---|
| Reading clues | Read all clues before deciding. |
| Anchors | Identify “must‑be” items first (e.g., ends, immediate neighbours). |
| Elimination | Write down impossible positions after each clue. |
| Pattern spotting | Memorize the 3‑person “A‑B‑C” pattern (A left of B, B left of C). |
| Time check | 1 min for 3‑clue puzzles, 2 min for 5‑clue puzzles. |
| Backtracking | Only revisit the last clue you used if contradictions arise. |
Pro‑Tip: While practicing, time yourself and note which types of clues consistently slow you down. Focus extra drills on those.
Final Thought
Puzzles are all about connect the dots—once you spot the fixed points, the rest follows like a domino chain. Keep your notes handy, practice relentlessly, and you’ll master the Goa TET reasoning puzzles in no time!
