How do I prepare for time and work for my cat?
Ram can finish the work in 10 days i.e. in one day he will do 1/10th of the work. Rahim can finish the work in 40 days i.e. in one day he will do 1/40th of the work. So, in one day, both working together can finish= (1/10) + (1/40) = 5/40 = 1/8th of the work. So, to complete the work they will take 8 days.
What is the easiest way to solve time and work questions?
Important Time and Work Formula
- Work Done = Time Taken × Rate of Work.
- Rate of Work = 1 / Time Taken.
- Time Taken = 1 / Rate of Work.
- If a piece of work is done in x number of days, then the work done in one day = 1/x.
- Total Wok Done = Number of Days × Efficiency.
- Efficiency and Time are inversely proportional to each other.
How can I learn time and work?
Time and Work Concepts, Tricks and Formulas | Time and Work Questions
- If a person A completes a work in X days, then the amount of work completed by him in 1 day will be = 1 X {1 \over X} X1.
- Similarly, if a person B completes work in Y days, then the amount of work completed by him in 1 day will be = 1 Y {1 \over Y} Y1.
How do you solve time and work problems?
FORMULAS
- The basic formula for solving is: 1/r + 1/s = 1/h.
- Let us take a case, say a person Hrithik.
- Let us say that in 1 day Hrithik will do 1/20th of the work and 1 day Dhoni will do 1/30th of the work.
Is time and work important for cat?
In CAT, Time and Work questions have become important, as a result of the rise in the number of questions from arithmetic. There are many shortcut formulas and tricks, which are frequently used to solve CAT Time and Work questions in quick time.
When they work alone B needs 25 more time to finish a job than a does?
When they work alone, B needs 25% more time to finish a job than A does. They two finish the job in 13 days in the following manner: A works alone till half the job is done, then A and B work together for four days, and finally B works alone to complete the remaining 5% of the job.
How do you calculate work time and efficiency?
efficiency = (10 + 20)% = 30%. This means in one day A and B together can do 30% of the work. Therefore, Number of days A and B together take to do 100% of work = (100/3) days = 3.33 days. Example 3: A can do a certain work in 12 days.
How do you solve work problems?
To solve a work word problem, multiply the hourly rate of the two people working together by the time spent working to get the total amount of time spent on the job. Knowledge of solving systems of equations is necessary to solve these types of problems.
What is chain rule in time and work?
Chain rule is used to find out this missing part of an element by subsequent comparison. The other given part of the same element is taken as base and is compared separately with all the other elements e.g. if you have a question having following elements: ‘men’, ‘days’ and ‘hours’.
How to solve time and work questions for cat?
Time and Work Tips to solve CAT questions: Assume the work to be the LCM of the numerical values given in the question. Get the one unit work for each of the participants who are mentioned in the question and are supposed to complete the work. Often the concepts of ratio and proportion are helpful in simplifying the complex calculations.
How are time and work questions easily solved?
Alternatively, Time and Work problems can easily be solved by the concept of the LCM method. Questions from Pipes and Cisterns also fall under Time and Work as the concept requires to solve such questions is the same as the concepts used to solve Time and Work Questions.
How is cat all about problem solving in the time constraint?
As CAT is all about problem-solving in the time constraint. This will fulfill dual purpose one is that we will learn how to solve them in the exam and the second is, we will know how to manage our own time. I know for many of you this topic can become very baffling and difficult to understand.
