Time Work Challenge is a quantitative reasoning game focused on time-work-rate problems. This foundational topic appears regularly in CAT, bank exams, SSC, and placement aptitude tests.
The game presents time-work scenarios requiring quick, accurate calculation. You develop the rate-based reasoning that helps solve this common exam topic efficiently.
The game covers time-work calculations:
Problem Types: • Basic Combined Work: Two or more working together • Alternating Work: Workers taking turns • Partial Work: Workers joining or leaving mid-task • Efficiency Variations: Different worker efficiencies • Work and Wages: Distribution based on contribution
Progressive Complexity: From basic to advanced variations.
Understand the work rates and conditions given.
Calculate work done per unit time for each worker/machine.
Use combined work rate to find total time.
Check if the answer makes sense practically.
Time Work Challenge develops quantitative abilities:
Rate Understanding: Grasping work-per-unit-time concepts.
Proportional Reasoning: Understanding rate relationships.
Problem Translation: Converting words to equations.
Quick Calculation: Mental math for rate problems.
Verification: Checking answers make practical sense.
Time-work is a core exam topic:
CAT Quant: Regular time-work questions in QA section.
Bank PO/Clerk: Common in quantitative aptitude.
SSC CGL/CHSL: Regular appearance in quant section.
GMAT Quant: Work-rate problems in problem solving.
Time Work Challenge benefits:
• CAT/GMAT Aspirants: Master this common topic • Bank Exam Candidates: Build quant section speed • SSC Aspirants: Strengthen core arithmetic • Placement Candidates: Prepare for aptitude rounds • Students: Build practical math skills
This game applies math learning research:
Conceptual Understanding: Rate concepts must be deeply understood.
Procedural Fluency: Practice builds calculation speed.
Problem Representation: Learning to translate words to math.
Transfer: Rate reasoning applies across many problem types.
Use LCM of days to assume total work - simplifies calculations
Calculate work done per day before combining workers
For efficiency problems, express rates relative to a baseline
Draw timelines for complex alternating or partial work problems
Verify that faster workers complete in less time
