FAQs on Basics: Time & Work Video Lecture - CSAT Preparation - UPSC

1. How do you calculate the time taken to complete a task when given the amount of work and the rate of work?
Ans. To calculate the time taken to complete a task, you can use the formula: Time = Work / Rate. Simply divide the amount of work by the rate of work to determine the time taken.
2. What is the relationship between time, work, and rate in a time and work problem?
Ans. In a time and work problem, time, work, and rate are related by the formula: Work = Rate x Time. This formula helps you calculate the amount of work done based on the rate at which it is being done and the time taken to complete it.
3. How can you determine the rate of work in a time and work problem?
Ans. The rate of work in a time and work problem can be determined by the formula: Rate = Work / Time. By dividing the amount of work by the time taken to complete it, you can find the rate at which the work is being done.
4. What is the concept of efficiency in time and work problems?
Ans. Efficiency in time and work problems refers to the rate at which a person or a group of people can complete a task. It is often expressed as a percentage and is used to calculate the amount of work that can be done in a given amount of time.
5. How can you calculate the total work done by multiple workers working at different rates?
Ans. To calculate the total work done by multiple workers working at different rates, you can use the formula: Total Work = (Rate1 x Time1) + (Rate2 x Time2) + ... + (Raten x Timen). Simply multiply the rate of each worker by the time they worked and sum up the individual work amounts to find the total work done.
