Nine boys can complete a work in 360 days, 18 men can complete the same work in 72 days and 12 women can complete it in 162 days. In how many days, can 4 men, 12 women and 10 boys together, complete the work ?

Arrange the following cases in ascending order in terms of number of days to complete the same work.

(A) P can do (1/3)rd of the work in 5 days.

Choose the correct answer from the options given below:

40 men can complete a work in 48 days. 56 men started for the same work for x days. After x days, 16 men increased, so, the remaining work is completed in $13\frac{1}{3}$ days. Find x?

X, Y and Z complete a work in 6 days. X or Y alone can do the same work in 16 days. In how many days can Z alone finish the same work?

Work done by A in one day is half of the work done by B in one day. Work done by B is half of the work done by C in one day. If C alone can complete the work in 35 days, then in how many days can A, B and C together complete the work?

4 men and 6 women can complete a job in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women take to complete the same job?
