Problems based on time and work which are asked in CAT can easily be solved by applying an alternate concept which is the method of LCM. In this article, I will be focusing on the application of this method. Question 1: Rakesh alone can do a work in 10 days. Brijesh can do the same job in 15 days. If both Rakesh and Brijesh work together, then in how many days the work will get completed? Rakesh can complete 30 units of work in 10 days. Similarly, Brijeh can complete 30 units of work in 15 days.

From the above example, it is clear that the method of LCM is not only simple to understand but also easy to apply. A student who is very new to this topic must deliberately apply this method wherever possible to get hold of the approach. Question 2: Arun, Barun and Tarun can do a work alone in 10, 12 and 15 days respectively. If all three work together then in how many days does the job get completed? Question 3: Tilak, Mukesh, and Sonali can complete a work in 10, 12 and 15 days respectively.

All three agree to complete the work together. After 2 days, Tilak leaves the work. Mukesh left the job 3 days before the completion of the work. Sonali alone continues until the work got completed. How many days did it take to complete the task? Assume that the total work is of 60 units and let us assume that it took X days for it to complete. Also, Mukesh left the work 3 days before the completion, so he worked for X-3 days.

From the above three examples, it is clear that the method of LCM is quite helpful in solving elementary questions based on time and work. There are other varieties of questions which are framed from time and work, and it is always advisable to solve all the variations to make oneself comfortable with this topic.

Let us discuss such types of questions from time and work, which frequently appear in competitive exams. If the same work is given to two people, say A and B, and if A is more efficient than B, then it is evident that A will take less number of days than B to complete the same work.

We can also deduce that efficiency is inversely proportional to the number of days taken to finish the job. Now, if they both work together, then the unit of work they can complete in one day equals one plus two i. Hence we can say that Rahul and Durgesh alone take 4 and 12 days respectively to complete the work. Let us take more questions based on the above concepts which will strengthen our understanding in solving problems related to time and work.

Question 1: Ram and Shyam working together can finish a work in 12 days. If Ram alone can do the same job in 20 days, then in how many days Shyam alone can complete the task? Question 2: Three friends, Akash, Bhairav, and Charan can do a piece of work in 12, 18 and 24 days respectively. They work at it together. Akash stops the job after 4 days, and Bhairav is called off two days before the work is finished. In how many days was the work completed? Question 3: Two candles of the same length are lighted at the same time.

The first is consumed in 6 hours and the second in 4 hours. Assuming that each candle burns at a constant rate in how many hours after being lighted was the first candle twice the length of the second? Also, let us assume that it takes x hours after which the first candle is twice the length of the second. Really, this is helpful for me and almost all type of problems trick covered by this site so this is helpful for me…. Your email address will not be published.

Question 4: Mayank can finish a work in 10 days. Mahesh is 2 times as efficient as Mayank. If they work together, in how many days will the work be completed? Question 5: Rahul is three times as good a worker as Durgesh and takes 8 days less than Durgesh to finish the work; find the amount of time required by Rahul and Durgesh working together to do the job?

В кадре возник мужчина в очках в тонкой металлической оправе, в руке он держал большой портфель. Выйдя на открытое место и бросив взгляд на корчащегося на земле Танкадо, он задвигал пальцами, словно исполнял ими какой-то причудливый танец над коробочкой, которую держал в руке. - Он работает на Монокле, - пояснил Смит.

В эпоху Возрождения скульпторы, оставляя изъяны при обработке дорогого мрамора, заделывали их с помощью сеrа, то есть воска. Статуя без изъянов, которую не нужно было подправлять, называлась скульптурой sin cera, иными словами - без воска. С течением времени это выражение стало означать нечто честное, правдивое. Английское слово sincere, означающее все правдивое и искреннее, произошло от испанского sin сега - без воска. Этот его секрет в действительности не был никакой тайной, он просто подписывал свои письма словом Искренне.

You can solve this problem using LCM method: Just take LCM of days in which A and B They work on alternate days, starting with A on the first day. So B starts to work and time taken by B to complete the work is (% of work left/%of work.
