Introduction to Data Sufficiency Scheduling

Data Sufficiency Scheduling problems present a scheduling question followed by two statements. You must determine if each statement alone, or both together, provide enough information to answer uniquely.

Prerequisites

Data sufficiency concepts Sufficiency vs necessity Unique answer requirement Logical assessment
Why This Matters: Data Sufficiency problems appear in 2-3 questions in CAT and GMAT. They test critical evaluation of information.

How to Solve Data Sufficiency Scheduling Problems

1

Step 1: Read the question - what needs to be determined?

2

Step 2: Analyze Statement I alone - can it answer uniquely?

3

Step 3: Analyze Statement II alone - can it answer uniquely?

4

Step 4: If neither alone, combine both statements

5

Step 5: Check if combined gives unique answer

6

Step 6: Select appropriate option

Pro Strategy: Test each statement independently. A statement is sufficient only if it yields exactly one possible answer.

Example Problem

Example: Question: What is the start time of the meeting? Statement I: The meeting starts after 10 AM. Statement II: The meeting starts before 11 AM. Solution: Step 1: Need specific time Step 2: Statement I alone → after 10 AM (many possibilities) → Not sufficient Step 3: Statement II alone → before 11 AM (many possibilities) → Not sufficient Step 4: Combined → between 10 AM and 11 AM (still many possibilities) → Not sufficient Answer: Neither statement sufficient

Pro Tips & Tricks

  • Options: A (I alone), B (II alone), C (both together), D (either alone), E (neither)
  • Don't use information from one statement while evaluating the other
  • Sufficient means unique answer, not just possible
  • If multiple answers possible, not sufficient

Shortcut Methods to Solve Faster

If question asks for exact value, range statements are usually insufficient alone
If two ranges overlap but don't pinpoint, combined may still be insufficient
If statements are identical, neither alone sufficient
Contradictory statements may still give unique answer sometimes

Common Mistakes to Avoid

Assuming statements are true (they are given as facts)
Using information from one statement while evaluating the other
Confusing 'sufficient' with 'necessary'
Not checking if answer is unique
