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
