Top 5 Videos on Work Rate and Time Quantitative Aptitude for MBA by Physics Wallah

A task that takes one person ten days may take less time when others join, but the answer depends on how much work each person can complete. Work Rate and Time questions test whether you can use this relationship across different situations, from people working together to pipes filling a tank. You may understand one type of question but need a different approach when the numbers, team size, or working schedule changes.

PW’s video lessons let you explore these situations one by one. Start with the foundation lesson to understand the link between work, rate, and time, then move on to combined work, Pipes and Cisterns, and group-based problems. As you practise these applications, you can get better at comparing contributions, working through calculations, and recognising which method suits each question in CAT Quantitative Aptitude.

Video 1: Master Work Rate and Time with Combined Work, Tables, and CAT Practice

Confused about how to calculate individual work rates when two or more people complete a task together? This lesson covers combined work, individual rates, LCM-based tables, changing schedules, remaining work, completion time, and payment division. It also includes group completion problems, logical subtraction, warm-up questions, homework, and CAT previous-year practice. The worked examples help you understand how the different values relate to each other and which calculations to use. Watch this lesson to practise a wider range of Work Rate and Time questions and improve your accuracy when solving schedule-based problems under CAT's time limit.

Video 2: Strengthen CAT Quantitative Aptitude with Time and Work 

This lecture by PW focuses on Time and Work as part of CAT Quantitative Aptitude, helping you practise the chapter's core problem types through worked examples. Use it to improve your understanding of work rates, calculate completion times, and approach questions involving multiple people more confidently. If you are building your arithmetic skills or revising this topic for CAT, this lesson gives you a focused opportunity to practise Time and Work and strengthen your problem-solving approach.

Video 3: Learn Work Rate and Time from Scratch with a CAT Foundation Lesson

Not sure how work, rate, and time connect when you solve CAT Quantitative Aptitude questions? This foundation lesson starts with the basics before introducing individual and combined work problems. You will practise using shared totals and tables when completion times are given, with examples involving A, B, and C working together, percentage changes, mental calculations, and people joining at different times. If you are new to Work Rate and Time or need to clear up basic concepts, this lesson helps you understand standard methods before moving on to more challenging CAT questions.

Video 4: Revise Work Rate and Time with Focused CAT Quant Practice

Work Rate and Time questions can become tricky when you need to compare rates, calculate completion times, or account for changes in working conditions. This lesson focuses on Work Rate and Time for CAT Quantitative Aptitude, giving you another opportunity to practise the chapter and apply its core methods. Use it to revisit key concepts, work through relevant question types, and check your calculations as you prepare for the exam. Whether you are revising the topic or strengthening your arithmetic skills, this lesson supports focused practice and helps you approach CAT questions with greater accuracy.

Video 5: Solve Group-Based Time and Work Questions with Efficient Calculations

Questions involving different workers, working hours, and changing team sizes can become confusing when you need to compare their efficiency. This lesson covers group-based Time and Work problems involving men, women, engineers, absent or additional workers, work duration, and payment division based on contribution. You also practise comparing total work under different conditions and using direct or inverse relationships to find unknown values. Watch this video after practising individual work rates to improve your ability to read data carefully, compare working conditions, and select suitable methods for group-based CAT Quantitative Aptitude questions.

Work Rate and Time becomes easier to practise when you understand the basics and then apply them to different question types. These five PW videos cover individual and combined work, changing schedules, Pipes and Cisterns, group efficiency, and payment calculations. Start with the foundation lesson if you need concept clarity, then move to application-based videos and practise the questions yourself. Regular revision can help you recognise patterns, avoid calculation errors, manage your time, and approach CAT Quantitative Aptitude questions with greater confidence.
