You must determine whether each statement alone, or both together, provide sufficient information to answer the question uniquely. These problems test your ability to evaluate information completeness without actually solving for the answer.
Prerequisites
How to Solve data_sufficiency_puzzle Problems
Step 1: Read the question carefully - what relationship needs to be determined?
Step 2: Analyze Statement I alone - can it answer the question uniquely?
Step 3: Analyze Statement II alone - can it answer the question uniquely?
Step 4: If neither alone is sufficient, combine both statements
Step 5: Check if both together provide a unique answer
Step 6: Choose the correct option based on standard DS answer choices
Step 7: Remember - 'sufficient' means a unique, definite answer
Example Problem
Example: Question: How is A related to B? Statement I: A is the father of C. Statement II: C is the brother of B. Solution: Step 1: Question asks for A-B relationship Step 2: Statement I alone: A is father of C, but no info about B → NOT sufficient Step 3: Statement II alone: C is brother of B, but no info about A → NOT sufficient Step 4: Combine: A is father of C, C is brother of B → A is father of B as well Step 5: Together they give unique answer (father) Answer: Both statements together are sufficient
Pro Tips & Tricks
- Statement alone is sufficient if it uniquely determines the relationship
- Gender ambiguity makes a statement insufficient
- Multiple possible relationships make a statement insufficient
- If statement gives partial information (e.g., 'A is parent of B'), it's insufficient (could be father or mother)
- The same information from both statements doesn't make them sufficient if each alone is insufficient
- Standard DS options: (1) Only I sufficient (2) Only II sufficient (3) Either I or II sufficient (4) Both together sufficient (5) Neither sufficient
