Boil the Egg


You want to boil a two-minute egg. If you only have a three-minute timer (hourglass), a four-minute timer and a five-minute timer, how can you boil the egg for only two minutes?

    Start 3-min and 5-min timers simultaneously. When 3-min timer finishes, start boiling the egg.

    As soon as 5-min timer finishes, egg would have boiled within those 2 minutes.

    If you start the 5-min and 3-min timers together than after 3 minutes have passed you are left with 2 minutes until the 5-min timer stops. So start boiling the egg
