A's 2 days work is equal to B's 3  days work. If A can complete the work in 8 days, then to complete the work B will take: 

A can finish work in 18 days and B in 36 days. If they work on it together for 9 days, what percent of work is left?

A is twice as efficient as B in writing novels. Together they can complete the task of writing a novel in 24 days. In how many days can A write the novel alone?

Panu, Jiban and Jalil can complete a certain task individually in 30, 20 and 60 days, respectively. Jiban started work on the task and Panu and Jalil agreed to help Jiban on every third day. How many days will it take to complete the task?

The ratio of the efficiencies of A. B and C is 7: 5: 4. Working together, they can finish a work in 35 days. A and B work together for 28 days. The remaining work will be completed (in days) by C alone:

A works 7 hours a day at the rate of 180 per hour. B works 5 hours a day at the rate of 160 per hour. What is the ratio of daily earnings of A and B?

If A, B and C can complete a piece of work in 6 days. If A can work twice faster than B and thrice faster than C, than the number of days C alone can complete the work is: 

‘A’ alone can complete a work in 6 days and “B” can complete this work alone in 8 days. They can complete this work in 3 days with the help of C. If they are paid Rs. 6400 for this work, then find the share of C.
