Can do a piece of work in 4 hours B and C together can do it in 3 hours while A and C together can do it in 2 hours how long will b alone take to do?
A can do a piece of work in 4 hours, B and C can do it in 3 hours. A and C can do it in 2 hours. How long will B alone take to do it? Hence B alone can do the work in 12 hours, so option [D] is correct answer.
Can do a piece of work in 24 days if B is 60\% more efficient than a then the number of days required by B to do the twice as large as the earlier work is?
We know that B is 60\% more efficient than A. So, the amount of work done by B in one day can be calculated as follows, Work done by B in 1 day =124+60100×124=10240+6240=16240=115. Therefore, the number of days required by B to complete the same quantity of work as A is 15 days.
Can do a piece of work in 18 days?
In 18 days, A can do a piece of work. ∴ In 1 day, A can do (1/18)th part of the work. ∴ In 12 days, A can do 12×(1/18) th part of the work = (12/18) = (2/3)rd part of the work. So, (1/3)rd of the work is completed by B in 8 days.
Can do any one job in 12 days and B is 60\% more work friendly than a tell me in how many days will that work be completed?
Since B is 60\% more efficient than A, the fraction of the total job completed on one day by B will be 60\% more than that of A. Hence B finishes the job in 7.5 days. Hence option [b] is correct.
Can do a piece of work in 10 days and B can do the same work in 20 days?
A can do a piece of work in 10 days, and B can do the same work in 20 days. With the help of C, they finished the work in 4 days. C can do the work in how many days, working alone? Explanation:Their combined 4 day work = 4(1/10 + 1/15) = 12/20 = 3/5.

How fast can A and B do the work in?
If A and B together can complete a work in 18 days, A and C together in 12 days, and B and C together in 9 days, then B alone can do the work in: A and B together can complete a work in 3 days. They start together but after 2 days, B left the work. If the work is completed after two more days, B alone could do the work in
