QL Mastermind Group - 1st Puzzle!
Hello Friends!
I am back from a mini vacation to India. Will get started right away with first ever post for this new group. Hope you all have fun solving it. Correct answer will be posted tomorrow morning (26th June 2007).
Question: My bath has two taps and a plug hole. The cold tap on its own fills the bath in 18 minutes, the hot one in 9 minutes. The plug hole can drain the bath in 15 minutes with the taps off. How long will the bath take to fill if I leave both taps on with the plug left out?
