Riddle of the Day

Alarm at Nine O'clock

I went to bed at eight o'clock in the evening and wound up my clock and set the alarm to sound at nine o'clock in the morning. How many hours sleep would I get before being awoken by the alarm?

Answer

You will only get 1 hour of sleep since wind-up alarm clocks do not discriminate between AM and PM. So when you set the alarm to sound at nine o'clock, the alarm will go off at both 9:00 AM and 9:00 PM.
