Answer» Three men can complete the work in 12 days.Thus, one man can complete the work in 36 days.Rate of work done by one man in 1 day =136Similarly, rate of work done by one woman in 1 day = 15×12=160 Now, six men will do 636, i.e., 16 unit of work in a day.Five women will do 560, i,e., 112unit of work in a day.∴ Total work done in 1 day= 16+112 = 14 unit Thus, six men and five women will take 4 days to complete the work. The work can be completed in 4 days. |
