Another challenging puzzle:
How many minutes would it be before six o'clock if fifty minutes earlier it had been four times as many minutes after three o'clock? Frank

It's 5:34pm now  so that 26 minutes before six is a quarter of 104 minutes past 3pm
(or 4:44pm) which is 50 minutes before 5:34pm Try this one... There are 100 doors, all closed. In a nearby cage are 100 monkeys. The first monkey is let out, and runs along the doors opening every one. The second monkey is then let out, and runs along the doors closing the 2nd, 4th, 6th,... all the evennumbered doors. The third monkey is let out. He attends only to the 3rd, 6th, 9th,... doors (every third door, in other words), closing any that is open and opening any that is closed. The fourth monkey does the same for the 4th, 8th, 12th, 16th,... doors, opening the closed ones and closing the open ones. The fifth monkey does the same to the 5th, 10th, 15th,... doors, and so on. After all 100 monkeys have done their work in this way, which doors are left open? One nice thing about this puzzle is that the number “100” is arbitrary. In fact, the question would still make sense, and still have the same answer, if the number of doors and monkeys was infinite! I found this particular puzzle via the NRO.com website. The answer is here http://www.magicities.com/hottrix/nojunk/answer.html

Good try, Range Cowboy, but I don't see how your answer works out to fit the question. The answer is: It would be 5:46, or 14 minutes to 6.
I'm going to have to sit for a while and try to figure the monkey and doors puzzle. This one looks hard!! Frank
