Three 24- hour clocks show the time to be 12 noon. one of the clocks is always correct , one loses a minute every 24 hours, and one gains a minute every 24 hours

The clock that gains a minute a day, after 60 days will indicate that it is 1: 00 p.m. when it is actually noon.continuing this way, in total it will take 60*24 or 1440 days before the clock is correct at noon again.similarly, the clock that loses a minute a day, after 60 days will indicate that it is 11: 00 a.m. when it is actually noon.again continuing this way, in total it will take 60*24 ir 1440 days before the clock is correct at noon again.in either case, all three clocks will indicate the right time after 1440 days.
