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?
Solution
Correct Answer: Option B
5 men = 19 days 3 men = 5/3 X 19 = 31.67 days 9 women = 19 days 6 women = 9/6 X 19 = 28.5 days 3 men + 6 women in 1 day = 1/31.67 + 1/28.5 = = 0.0315756 + 0.0350877 = 0.0666633 = 667 / 10,000 So they will complete the work in 10,000/667 = 14.99 days
