Case of Two Clocks
Mr. Tito while collecting data for census came across this peculiar old lady, who was living alone in a very old and big house. She refuses to tell her age until, he answers her question correctly.
"I have two old clocks in my house, one of them does not run at all and the other always loses an hour a day." She said. "And since I don't have any other clock, I have to look into one of the two clocks. the question is, which one should I rely on for any particular week?"
Stumped by the question, Mr. Tito came back, and is having nightmares over the case of two clocks, can you help ?

duh.. rely on the one that looses an hour a day... probably from 12 to 1 or 1 to 2... which ever is naptime... that one stop tickin... she probably dead.
You can say the broken one as twice a day that clock is correct where as the other clock isn't
If the object is to use both clocks, set the moving one to the correct time and the non working one to 12. Each morning, wake up and move the non-working clock forward one, add that much each day.
Of course, if you're going to do that, just wake up and put the working one forward an hour each day.
I'm fairly certain that a stopped clock is no good for telling time any day of the week.
Another thought occurs, she doesn't say "rely on to tell the time"
So if you can think of another reason to rely on an old clock on a weekly basis, maybe you can come up with a use for a dead clock.
Maybe they remind her of dialysis day or something.
gbusman you would be correct but how would she set it to the right time if she said she has no other clock ????? :/
She should make a sundial, and I would say Listen old hag tell me your age or I will call the cops
Also i would say rely on the one that doesn't run, because it is right 14 times a week, on the other hand the clock that loses an hour is only right once every 2 weeks
Mr. Tito thanks his lucky stars they only conduct the census once every ten years.
well after thinking about it i would actually rely on the one that loses and hour, because after 12 days it will be at the time in which it is because there are no a.m. and p.m. on the clocks, assuming of course they are grandfather clocks
If she doesnt have a clock, how does she know her age?
she should rely on the clock that doesn't run because as we all know clocks can't run they stay still
the question is to know particular week. the answer should be every 7 hours late due to the death clock's is a week
Well I don't think I can answer the question but there is a way to use both clocks to effectively tell you the time.
The clock that doesn't run, you can set it to 12 on the first day and set the clock that is slow to the correct time on that day.
The next day, simply set the clock that doesn't run to 1 so that you know 1 day has passed and that you need to add an hour to whatever time you're reading from the slow clock.
Repeat for day 3 so that the clock that doesn't run is set to 2 so that you know the slow clock is 2 hours behind. When you get to 12 hours, the cycle repeats again.
I think that she should rely on the one that does not run. Because if I am not mistaken, sundials do not run?
I am not really sure I understand the question properly, but I think that will be my best answer. ^___^;
why cant she just get a new clock
every 12 days they will both have the correct time of what is on the broken one.
it is day light savings so, she resets her clock and there
Being old clocks we will assume that the dial has the 12 number values.
The working clock is losing an Hour a day thus runs a 12-Day cycle to reach the same matching time of the broken clock. Seven (a week) and Twelve (hours) have no common denominator so it takes 12 weeks for both clocks to reach the exact time again in exact weeks. During the twelve week the two clocks will be correctly match 7 times.
The broken clock will be correct 2 times a day, 14 times a week and 168 times in 12 weeks.
Since neither clock will ever be more than 6 hours off, the clock with the most correct times would have to be the most accurate clock, making the broken clock the most accurate clock no matter what the week.
That result would also be true with 24 Hour Military time clocks.
The best solution is to Trade The Working clock for your watch (she now has the two most accurate clocks), get your sale, have the clock fixed (probably cheaper than fixing the broken one) and keep or sell the antique clock.
If one clock doesn't *run* perhaps it IS a Sundial and is accurate in keeping time?
ANSWER the broken clock
-------------------------
Details
-------------------------
Broken clock will show correct time twice a day i.e. a total of 14 times a week.
The clock which loses one hours a day will be correct once every 12 days
So the broken one is more accurate
GOT RIGHT

and thanks to BigSpud for a great explaination.
Mr. Tito has several options: waste time figuring it out, kill anyone who doesn't give him a straight answer, demand a raise, find a new job, etc.
