PROBLEM IS AS FOLLOWS:

A clock that strikes only the hours has struck a total of 21 times in the last 2.5 hours. Seconds ago, it just finished striking the hour. What hour?

 

Please also provide a clear explination as to how in the world a clock can strick 21 times in 2.5 hours (As far as i know 21 hours does not equal 2 hours)

Thank you.

Seconds ago, the clock struck 8 o'clock.                0 hours   

One hour earlier, it struck 7 o'clock.                        1 hour  

One hour before that, it struck 6 o'clock.                 2 hours

30 minutes before that, no noise.                             2.5 hours

I only just answered this question an hour or so ago.

Why did you ask it twice in a row!

You posted them within minutes of each other!

 

Besides,

If you want to repost you give the address of the original and ask people to answer on the original thread.
