'A' can do 2/3 of a work in 24 days and 'b' can do 1/4 of work in 3 days in how many days they can do it together. |
|
Answer» -step explanation:This can be solved by first finding the work DONE by A and B in 1 day.Therefore, work done by A in one day=1/3 per dayand, work done by B in one day = 1/4 per dayNow to FIND the amount of work done, by both of them, in one day=(1/3+1/4) per day=7/12 per dayThus A and B will take 12/7 DAYS to COMPLETE a work, i.e. 1 day 17 hours (approximately). |
