FAQs on Advanced Concepts of Time & Work - 1 Video Lecture - Quantitative Aptitude (Quant) - CAT
| 1. What are the basic principles of time and work problems in CAT? |  |
Ans. The basic principles of time and work problems involve understanding the relationship between the time taken to complete a task and the work done. If a person can complete a job in 'x' days, their work rate is 1/x jobs per day. When multiple people work together, their combined work rates add up, allowing us to calculate the total time taken to complete the job.
| 2. How can I solve time and work problems involving multiple workers? | |
Ans. To solve time and work problems involving multiple workers, first determine the work rates of each worker individually. Then, add their work rates together to find the combined work rate. Finally, use the formula: Total work = Combined work rate × Time to find the time required to complete the job when all workers are working together.
| 3. What formulas are commonly used in time and work problems? | |
Ans. Common formulas used in time and work problems include:
1. Work = Rate × Time
2. Rate = Work / Time
3. Time = Work / Rate
These formulas can help in calculating individual or combined work rates and the time required to complete tasks.
| 4. How do I approach problems with varying work rates among workers? | |
Ans. For problems with varying work rates, first, determine the individual work rates of each worker. If one worker is faster than another, you can express their rates in a ratio. Use this ratio to find the total work done and apply the combined work formula. This will allow you to calculate the total time taken for the task.
| 5. Are there any shortcuts or tricks for solving time and work questions in CAT? | |
Ans. Yes, some shortcuts include:
1. Using the concept of 'man-days' to simplify calculations.
2. Recognizing patterns in ratios of work rates.
3. Understanding that if a person can complete a job in 'x' days, they can complete 1/x of the work in one day.
These tricks can help save time and improve accuracy during the CAT exam.
