InterviewSolution

1.	If `M_(1)` men can complete a wrk in `D_(1)` days and `M_(2)` men can complete the same work in `D_(2)` days, write the formula relating them. Given that the number of men at work is inversely proportional to the number of days.
Answer» Given, `M_(1)=D and M_(2)=D_(2)` Also, `Mprop(1)/(D)` `impliesMD=`constant. `therefore(M_(1))/(M_(2))=(D_(2))/(D_(1))` `impliesM_(1)D_(1)=M_(2)D_(2)`
