Question

During rainy season, huge inflow of water takes place into a reservoir. Measures are taken to clear the reservoir while water keeps flowing into it at a constant rate. It has been observed that seven and five men can clear the reservoir in 20 and 50 days, respectively, with the initial quantity of water in the reservoir being 24 and 36 kilolitres, respectively. What is the rate of inflow of water into the reservoir in litres per day?

Answer 1

assuming each man can x liters/day, then if the inflow rate is y liters/day, we have
24000+20(y - 7x) = 0
36000+50(y - 5x) = 0
x = 240
y = 280

Answer 2
