Reasoning: How to Solve Decoding by Analogy Pattern Recognition in Given Examples

Introduction "Decoding by Analogy typically carries 20-30 marks in competitive exams, making it a must-master topic to crack the exam quickly and confidently."

WHAT YOU NEED TO KNOW FIRST To solve Decoding by Analogy questions, you need to have a basic understanding of:

1. Direction Chart: A chart that shows the direction of movement (e.g., north, south, east, west) and the corresponding directions (e.g., up, down, left, right).
2. BODMAS: A rule to follow when solving mathematical expressions: Brackets, Orders, Division, Multiplication, Addition, and Subtraction.
3. Sitting Arrangement Conventions: Rules to follow when arranging people in a room, such as:
   • North is always at the top.
   • East is always on the right side.
   • South is always at the bottom.
   • West is always on the left side.

CRYSTAL‑CLEAR METHOD (Step‑by‑Step) To solve Decoding by Analogy questions, follow these steps:

1. Read the question carefully: Understand what is being asked and what information is given.
2. Identify the pattern: Look for a pattern or relationship between the given examples.
3. Create a table or chart: Organize the information into a table or chart to help you see the pattern more clearly.
4. Look for a rule or formula: Try to find a rule or formula that explains the pattern.
5. Apply the rule or formula: Use the rule or formula to solve the problem.
6. Check your answer: Verify that your answer makes sense and is consistent with the given information.

WORKED EXAMPLES

Example 1 – Easy A, B, C, D, E are sitting in a row. A is sitting at one of the ends. B is sitting next to E. C is sitting next to A. Who is sitting at the other end?

Step 1: Read the question carefully. Step 2: Identify the pattern: A is at one of the ends, B is next to E, C is next to A. Step 3: Create a table or chart: | Person | Position | | --- | --- | | A | End | | B | Next to E | | C | Next to A | Step 4: Look for a rule or formula: Since A is at one of the ends, and C is next to A, C must be at the other end. Step 5: Apply the rule or formula: C is sitting at the other end.

What we learned: Pay attention to the given information and look for a pattern or relationship between the examples.

Example 2 – Medium A, B, C, D, E are sitting in a row. A is sitting at one of the ends. B is sitting next to E. C is sitting next to A. D is sitting next to B. Who is sitting at the other end?

Step 1: Read the question carefully. Step 2: Identify the pattern: A is at one of the ends, B is next to E, C is next to A, D is next to B. Step 3: Create a table or chart: | Person | Position | | --- | --- | | A | End | | B | Next to E | | C | Next to A | | D | Next to B | Step 4: Look for a rule or formula: Since A is at one of the ends, and C is next to A, C must be at the other end. Step 5: Apply the rule or formula: C is sitting at the other end.

What we learned: Pay attention to the given information and look for a pattern or relationship between the examples. Also, be careful not to overlook any information.

Example 3 – Exam‑Style Five friends - A, B, C, D, and E - are sitting in a row. A is sitting next to C. B is sitting next to E. D is sitting next to A. Who is sitting at the other end?

Step 1: Read the question carefully. Step 2: Identify the pattern: A is next to C, B is next to E, D is next to A. Step 3: Create a table or chart: | Person | Position | | --- | --- | | A | Next to C | | B | Next to E | | D | Next to A | Step 4: Look for a rule or formula: Since A is next to C, and D is next to A, D must be next to C. Step 5: Apply the rule or formula: D is sitting next to C. Step 6: Check your answer: Verify that the answer makes sense and is consistent with the given information.

What we learned: Pay attention to the given information and look for a pattern or relationship between the examples. Also, be careful not to overlook any information.

Common Mistakes

MISTAKE → WHY IT HAPPENS → CORRECT APPROACH 1. Not reading the question carefully: Not understanding what is being asked.
Correct approach: Read the question carefully and understand what is being asked. 2. Not identifying the pattern: Not seeing the relationship between the examples.
Correct approach: Look for a pattern or relationship between the examples. 3. Not creating a table or chart: Not organizing the information.
Correct approach: Create a table or chart to help you see the pattern more clearly. 4. Not looking for a rule or formula: Not trying to find a rule or formula that explains the pattern.
Correct approach: Look for a rule or formula that explains the pattern. 5. Not checking your answer: Not verifying that the answer makes sense.
Correct approach: Check your answer to verify that it makes sense and is consistent with the given information.

EXAM TRAPS

Trap → How to Spot it → How to Avoid it 1. Trick question: A question that is designed to trick you into giving a wrong answer.
How to spot it: Look for a question that is too easy or too hard.
How to avoid it: Read the question carefully and understand what is being asked. 2. Misleading information: Information that is given to distract you from the correct answer.
How to spot it: Look for information that seems irrelevant or unnecessary.
How to avoid it: Focus on the relevant information and ignore the irrelevant information. 3. Ambiguous language: Language that is unclear or open to interpretation.
How to spot it: Look for words or phrases that are unclear or ambiguous.
How to avoid it: Read the question carefully and ask yourself what the question is asking.

TIME‑SAVING SHORTCUTS

1. Elimination trick: Eliminate options that are clearly wrong or impossible.
2. Diagram hack: Use a diagram to visualize the problem and find the solution.
3. Pattern recognition: Recognize patterns and relationships between the examples to find the solution.

1‑MINUTE RECAP "Alright, let's recap the strategy for Decoding by Analogy. First, read the question carefully and understand what is being asked. Then, identify the pattern or relationship between the examples. Create a table or chart to help you see the pattern more clearly. Look for a rule or formula that explains the pattern and apply it to find the solution. Finally, check your answer to verify that it makes sense and is consistent with the given information. Remember to avoid common mistakes and exam traps, and use time-saving shortcuts like elimination tricks and diagram hacks. You got this! Good luck on your exam."
