FAQs on Time and Work - 7 Video Lecture - Crash Course for SSC CGL (English)
| 1. What is time and work in SSC CGL? |  |
Ans. Time and work is a concept in the SSC CGL exam that deals with the relationship between the time taken to complete a task and the number of workers involved. It involves solving problems where the work done by each worker or the time taken to complete a task is given, and we need to find the total work or the number of workers involved.
| 2. How can I 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 rate of work: Determine the work done by each worker per unit of time.
2. Calculate the total work: Multiply the rate of work by the total time taken to complete the task.
3. Find the number of workers: Divide the total work by the work done by each worker per unit of time.
4. Solve for the desired quantity: Depending on the problem, you may need to find the total work, the time taken, or the number of workers.
| 3. What are the different types of time and work problems in SSC CGL? | |
Ans. There are various types of time and work problems in SSC CGL, including:
1. Direct Proportions: When the work done is directly proportional to the number of workers or the time taken.
2. Inverse Proportions: When the work done is inversely proportional to the number of workers or the time taken.
3. Combined Work: When multiple workers are involved, and their individual rates of work need to be combined to find the total time or work.
| 4. Can you provide an example of a time and work problem in SSC CGL? | |
Ans. Sure! Here's an example:
If it takes 8 hours for 4 workers to complete a task, how many hours will it take for 6 workers to complete the same task?
Solution:
Let's assume that the work done is constant.
For 4 workers, the time taken is 8 hours, so the rate of work is 1/8.
For 6 workers, we can use the formula: (Rate of work) x (Time taken) = 1 (as the work done is constant)
So, (1/8) x (Time taken for 6 workers) = 1
Time taken for 6 workers = 8/6 = 4/3 hours.
| 5. Are there any shortcuts or tricks to solve time and work problems in SSC CGL? | |
Ans. Yes, there are a few shortcuts that can help in solving time and work problems more efficiently:
1. Reciprocal Method: Instead of calculating the rate of work, you can calculate the time taken directly by taking the reciprocal of the number of workers or the rate of work.
2. Unitary Method: If the rate of work is given in terms of fractions or percentages, you can convert it into the work done by a single worker in one unit of time (e.g., 1 hour or 1 day) and use that to solve the problem.
