FAQs on Time and Work - 2 Video Lecture - Crash Course for SSC CGL (English)

1. How to solve time and work problems in SSC CGL?
Ans. To solve time and work problems in SSC CGL, you can follow these steps: 1. Identify the total work involved in the task. 2. Determine the rate at which each person or machine can complete the work. 3. Use the formula: Time = Work / Rate to find the time taken by each person or machine. 4. If multiple people or machines are working together, add their individual times to find the total time taken to complete the task.
2. 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 machine can complete a task. It is usually represented as a fraction or percentage. The higher the efficiency, the faster the work can be completed. In the context of time and work problems, efficiency is often used to calculate the time taken by each person or machine to complete a task.
3. How to solve problems involving both work done and time taken in SSC CGL?
Ans. To solve problems involving both work done and time taken in SSC CGL, you can use the formula: Work = Rate × Time. 1. Identify the work done by each person or machine. 2. Determine the time taken by each person or machine. 3. Use the formula to calculate the rate at which each person or machine is working. 4. If multiple people or machines are working together, add their individual rates to find the total rate. 5. Use the total rate and the given time to calculate the total work done.
4. How to solve problems involving fraction of work done in SSC CGL?
Ans. To solve problems involving fractions of work done in SSC CGL, you can follow these steps: 1. Identify the total work involved in the task. 2. Determine the fraction of work done by each person or machine. 3. Calculate the work done by each person or machine by multiplying the total work with their respective fractions. 4. If multiple people or machines are working together, add their individual work done to find the total work done.
5. Can time and work problems be solved using ratios in SSC CGL?
Ans. Yes, time and work problems can be solved using ratios in SSC CGL. Ratios can be used to represent the relative rates at which different people or machines work. By comparing the ratios, you can determine the share of work done by each person or machine. Ratios can also be used to find the time taken by each person or machine if the total work is known.
