Work is defined as

Work is defined as Correct Answer Force over a distance

The correct answer is Force over a distance.

Key Points

  •  Work-
    • ​It is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
    • If the force is constant, work may be computed by multiplying the length of the path by the component of the force acting along the path.
    • To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd.
    • If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
    • Work done on a body is accomplished not only by a displacement of the body as a whole from one place to another.

Given below are two quantities named 1 and 2. Based on the given information, you have to determine the relationship between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity 1: P and Q can do a work in 6 days and Q and R can do a work in 60/7 days and P and R can do a work in 20/3 days. If Q and R work for first 2 days and left the work. Find the total time taken by P to complete the remaining work. Quantity 2: A and B can do a work in 8/3 days, B and C can do the same work in 3 days and A and C can do the same work in 24/5 days. In what time C alone can complete the work?
You are given a question and two statements. Idientify which of the statements is/are sufficient to answer the question. Question: In a city, some people travel to work by bus, some people travel to work by train, some people travel to work by both bus and train, and some travel to work neither by bus, nor by train. The number of people who travel to work by both bus and train is how much less than the number of people who travel to work by neither? Statements: (1) In the city, there are 384 people who travel to work by bus. (2) In the city, there are 672 people who travel to work by train,
A, B, and C can do a piece of work in 20 days, 30 days, and 15 days respectively. They start the work together but after 3 days they leave the work and the work is stopped for the next 15 days. After that D, E and F joined the work and did the work alternately and D started the remaining work. If D’s efficiency is twice A, E’s efficiency is half of B and F is equally efficient as C. So find in how many days D, E, and F complete the remaining work.
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: A can do a piece of work in 10 days and B can do the same work in 15 days. They start working together and after 4 days, A left the work. Find in how many days the total work will be completed. Quantity B: P can do a piece of work in 15 days and Q can do the same work in 25 days. They start working together and after 5 days, Q left the work. Find in how many days the remaining work will gets completed.
A and B together can do a piece of work in 10 days. If A can do the work in 15 days, find in how many days that B alone can do the same work. Given below are the steps involved in solving the above problem. Arrange them in sequential order. (A) One day’s work of B is 1/10 - 1/15 (B) One day’s work of A and B is 1/10 and one day’s work of A is 1/15 (C) B alone can do the work in 30 days (D) One day’s work of B is 1/30
Five men A, B, C, D and E can do a piece of work in 20, 10, 30, 40 and 50 days respectively. A, B, and C started the work and they work for 2 days after which A and B left the work and D joins the work. D and C work another 3 days together after which C leaves and E joins the work. Find in how many days E and D completed the rest of the work.
Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A: M and N can complete the work in 10 and 20 days respectively. They started doing work together but after 4 days M left the work. In what time N can complete the remaining work? Quantity B: A and B can together complete the work in 12 days. A alone can complete the work in 30 days. If B works for first 4 days alone and then A joins the work, in how many days remaining work will be complete?
P can complete ¼ of some work in 10 days, Q can complete 40% of the same work in 48 days. R completes 1/8 of the work in 5 days and S does 1/10 of the work in 2 days. ½ of total work is done by (Q + R) and remaining work is done by (P + S). What will be the ratio of the days for completing ½ of work by (Q + R) and remaining work by the (P + S)?

Paddy transplantation in Punjab is a very hard labor-intensive back-breaking job. In the transplant season, teams of special people swarm the entire rural landscape employed by the farmers and can be seen laboring away in the fields under the hot sweltering sun. Farmer Jagtar Singh has a full-time help at his sprawling farm who goes by the name of Hari, and who hails from Allahabad, UP. During the paddy transplant season, it is up to Hari to rope in his brothers, sons, and cousins from his native village to complete the task well in time. All his people are skillful and masters of the trade and equally efficient at their jobs. So, this past season, this is how the work went. Hari started the work and after 't' hours was joined in by his brother Jaggi. After another 't' hours, Neelu, their cousin, also jumped into the fray. So, after every 't' hours, 1 person kept on joining the team of already working men, and this process kept on continuing till the completion of the work. The last person worked for 't' hours. In the last season, the very same men had completed the same work working 2 shifts of 12 hours all of them working simultaneously owing to some peculiar weather conditions and time constraints. Jagtar Singh is a fair and just paymaster which is why he faces no labor shortage at this crucial time and which is why the whole 'Hari clan' are more than happy to work for him and are at his beck and call. He pays each of them individually proportional to the work done by them. This time around, Hari received 11 times as much as Surinder, his eldest son, who was the last person to join in. In how much time was the work completed?
