What's the Time? (Posted on 2003-07-30) Difficulty: 2 of 5
At a certain time I looked at a 24 hour digital clock and noticed some things about the time:

1)The number in the hours section plus the number in the minutes section makes 60.

2)One of the digits in the minutes section is the square root of the other digit in the minutes section.

3)The sum of the digits in the minutes section is the number in the hours section reversed. What was the time?

From clue 2 we know the time has to be : ??:00, ??:11, ??:24, ??:42 or ??:39.

For clue 1 to work the times would have to be : 60:00, 49:11, 36:24, 18:42 or 21:39. Of these only 18:42 and 21:39 could show up on a 24 hour clock.

4+2 does not equal 81 so 18:42 doesn't work for clue 3. 3+9 does equal twelve, so the time was 21:39.
