Two workers A and B working together completed a job in 5
days. If A worked twice as efficiently as he actually did and
B worked 1/3 as efficiently as he actually did, the work would
have completed in 3 days. Fine the time for A to complete
the job alone.

Two workers A and B working together completed a job in 5 days. If A worked twice as efficient, as he actually did and B worked 1/3 as efficiently as he actually did, the work would have been completed in 3 days. A alone could complete the work in 5 1/4 d a y s b. 6 1/4 d a y s c. 7 1/2d a y s d. none of these

Two workers 'A' and 'B' working together completed a job in 5 days. Had 'A' worked twice as efficiently as he actually did, the work would have completed in 3 days. In how many days could 'A' alone complete the job ?

(A + B) can do a piece of work in 5 days. If A works with twice of his efficiency and B works with (1)/(3) of his efficiency, then work will be completed in 3 days. In how many days will A do this work alone ?

A and B working together can complete a job in 30 days. The ratio of their efficiencies is 3 : 2. In how many days can the faster person complete the job?
