The ratio of work done by 30 women to the work done by 25 men in the same time is 5:6. If 9 women and 10 men can finish a work in 3 \(\tfrac{1}{13}\) days, then how many women can finish the work in 4.5 days?

1. 18
2. 16
3. 20
4. 25

Correct answer: 16

Solution

The ratio gives the relative efficiency of a woman and a man. Using the time taken by 9 women and 10 men, we can find the total work and then determine how many women are needed to complete the same work in 4.5 days. The result is 16 women.

• A certain number of men can complete a work in six hours less than the time taken by some women. Work completed by one man in one hour is the same as the work completed by one woman in one hour. Which of the following ratios of the number of men to the number of women can satisfy the given condition?
• November: Each flat is supplied by a tap with a flow rate of 250 L/h, and only 50% of the flats are occupied in November. The water tank provides continuous water supply to these taps throughout the month. December: In this month, 30 flats are occupied and the tank gets emptied after 4\(\tfrac{1}{6}\) days. The flow rate from one tap in December is A% more or less than the flow rate in November. January: The flow rate of water from the taps is the same as in November, and the tank gets emptied after supplying water to the building for 100 hours. The number of flats occupied in January is B%. In November, how many times does the tank need to be filled?
