If 5 men or 9 women can do a piece of work in 19 days, then in how many days will 3 men and 6 women do the same work? Let us assume the total work done by the men/women be 19*5*9 = 855 units. Now, 3 men and 6 women would do, 3*9 + 6*5 or 57 units of the work in a day.
Answer:
15 days
Step-by-step explanation:
Let us assume the total work done by the men/women be 19*5*9 = 855 units.
Since 5 men do the work in 19 days, 1 man does 19*9 = 171 units in 19 days and 9 units in a day
Since 9 women do the work in 19 days, 1 woman does 19*5 = 95 units in 19 days and 5 units in a day
Now, 3 men and 6 women would do, 3*9 + 6*5 or 57 units of the work in a day.
Therefore, it will take 3 men and 6 women a total of:
855/57= (19∗5∗9) / (19∗3) = 15days
