B is 4/3 times as efficient as A. If A can complete 5/8th of a given task in 15 days, what fraction of the same task would remain incomplete if B works on it independently for 10 days only ?
Note: Fractions printed stacked in source. Options (2) and (5) are both 2/3 as printed in source.
B is 7.5 times as efficient as A. If A can complete 6/7th of a given task in 12 days, what fraction of the same task would remain incomplete if B works on it independently for 6 days only ?
A can complete a task in 15 days B is 50% more efficient than A. Both A and B started working together on the task and after few days B left task and A finished the remaining 1/3 of the given work. For how many days A and B worked together.
Note: "1/3" is a stacked fraction in source
Efficiency of B is two times more than efficiency of A. Both started working alternatively, starting with B and completed the work in total 37 days. If C alone complete the same work in 50 days then find in how many days A and C together will complete the work?
Note: Answer check: 'two times more efficient' is ambiguous; the source key (30 days) only works if B is 3 times as efficient as A.
7 men and 6 women together can complete a piece of work in 8 days and work done by a women in one day is half the work done by a man in one day. If 8 men and 4 women started working and after 3 days 4 men left the work and 4 new women joined then, in how many more days will the work be completed

16 children can complete a task in 12 days working 4 hours a day. Find in what time 10 women will complete the same task with 60% more efficiency than that of a child working 6 hours a day?
Note: source key says (c) but its own worked solution ends 'y= 8 days' (option d); answer kept as printed
B is 20% less efficient than A, who completes a work in 72 days. C alone can complete the same work in 60 days. If all three started working alternatively starting with A and followed by B and C respectively, then find in how many days the work will be completed?
A can do a piece of work in 24 days. B can do the same work in 16 days and C can do the same work in 5/4th time required by both A and B together. A and B work together for 6 days, then C complete the remaining work. How many day did C work ?
