A short introduction

Solution to: Three Taps

The smallest tap fills 1/20 water-cask in 1 minute. The middle tap fills 1/12 water-cask in 1 minute. The largest tap fills 1/5 water-cask in 1 minute.

Together they fill 1/20 + 1/12 + 1/5 = 1/3 water-cask in 1 minute. Therefore, the whole water-cask is filled in 3 minutes.
