It was calculated that 75 men could complete a piece of work in 20 days.
When work was scheduled to commence, it was found necessary to send 25
men to another project. How much longer will it take to complete the work?

A man was engaged on a job for 30 days on the condition that he would get a
wage of Rs. 10 for the day he works, but he have to pay a fine of Rs. 2 for
each day of his absence. If he gets Rs. 216 at the end, he was absent for work
for ... days

If 6 men and 8 boys can do a piece of work in 10 days while 26 men and 48 boys can do the same in 2 days, the time taken by 15 men and 20 boys in doing the same type of work will be:

10 women can complete a work in 7 days and 10 children take 14 days to complete the work. How many days will 5 women and 10 children take to complete the work?

A can finish a work in 18 days and B can do the same work in 15 days. B worked for 10 days and left the job. In how many days, A alone can finish the remaining work?

X can do ¼ of a work in 10 days, Y can do 40% of work in 40 days and
Z can do 1/3 of work in 13 days. Who will complete the work first?

If A can complete a work in 10 days and B is 100 faster than A.
How much time B will take to complete the work?

A group of men completes a work in 10 days, but five of them are
absent and so the rest do the work in 12 days. Find the original number of Men.

A can do a certain work in 12 days. B is 60% more efficient than A. How many
days does B alone take to do the same job?

A can do a piece of work in 7 days of 9 hours each and B alone can do it in 6 days
of 7 hours each. How long will they take to do it working together 8 2/5 hours a day?
