Sample previous-year questions
Mohan and Sohan can do a piece of work in 18 days, Sohan and Shyam can do the same work in 24 days, and Mohan and Shyam can do that work in 36 days. In how many days will Mohan, Sohan and Shyam together do the same work ?
A man can do a work in 10 days. The man along with a boy can do the same work in 8 days. What is the ratio of efficiencies of work of the man and the boy?
Ayush and Bilal can do a job in 'D' days. If Ayush can alone do the job in D+3 days and Bilal alone can do the job in D+12 days, find the value of D.
Mohan can do a piece of work in 7 days working 9 hours a day and Shyam can do the same work in 6 days working 7 hours a day. How long will they take to complete the job working together and 8(2/5) hours a day?
Two persons A and B finish a work in 10 days. A is twice as efficient than B. How many days A will take to finish the work, if he has to do it alone ?
Working 9 hours a day, 12 persons complete a work in 25 days. Working 6 hours a day, 15 persons can do the same work in
60 persons consume 300 kg of wheat in 40 days. In how many days will 25 persons consume 100 kg of wheat?
'A' takes twice as much time as 'B' to complete a work and 'C' does it in the same time as both 'A' and 'B' together do it. If all three of them work together and complete the work in 5 days, then the time taken by 'B' to complete the work alone is :
