Thread: New riddle

Yeah - tricky ain't it. Can be done though. Judging by the times provided by kiwigeo, it seems that you might be reading the question wrong, rather than being rough at maths!

Just to point you in the right direction, it was the one that stopped which had been gaining. Also, the answer I'm looking for, is the time that the other (correct, still running) clock is showing now (1.5 hours later).

Okay okay..I thtink Ive got it (typing amidst a pile of screwed up bits of paper and worn out batteries from the HP41)


04:29 and thats my last offer.

No its definitely the maths.....had a first year maths teacher when I was 16 and he managed to destroy my enthusiasm in maths.

I mentioned my brother being a teacher.....the little so and so went teaching on his first assignment at the same school we went to as students....and became good buddies with my old teacher.

Okay I see whats going wrong here....thought the clock was running slow.


Too early in the day to be doing this sort of stuff....should be working anyway.

Well I bet the correct answer is on one of those bits of paper!

I will say one last 'clue' ... Each of your answers is moving in the right direction!

If the clock that stopped was correct, the time now would be 6:18 (1.5 hours later). As it was gaining, the true time will be earlier than that, but not quite as early as your tries!

04:30 hours.......

Im gonna kill my brother...and that bldi maths teacher

Two clocks were correct at midnight but then one began to gain four minutes every hour. It stopped one and a half hours ago showing 4:48 pm. The clocks run for less than 24 hours.
What time will the other clock be showing ?

Im not reading this right..

Okay....step by step and slow deep breaths

1. Two clocks....Clock A and B
2. Clock A and B read same time at midnight.
3. Clock B gains 4 minutes every hour cf with Clock A.
4. Clock B stops showing 04:48. ie it has run for 4 hours and 48 minutes.
5. Clock B stopped 1.5 hours ago <====== this I dont understand. 1.5 hours relative to what time?
6. Clocks run for less than 24 hours.

Is this correct?

The clock thats still running (and showing correct time) will be showing what ever time it is right now.

The clock thats still running (and showing correct time) will be showing what ever time it is right now.

Your turn, simon c

Whilst eagerly awaiting a brain teaser from Simon C, I thought I’d throw this one in the mix to keep your grey matter active.

"You are walking towards a town when you come to a fork in the road. You do not know if the town is left or right. You decide to ask some people in the houses along the way. Nobody knows but they tell you there are twins in a house across the road that know. However one of them always lies and one always tells the truth. You don not know which one is going to answer the door. You may only ask one question.(Not one to each twin) What do you ask and which way do you go?"

(ps feel free to cut in with a new question Simon ! I hope I don’t get attacked by the ‘not your turn nazi’s’)

You say to either of the twins, "which road would he say", pointing to the other twin. Whatever that twin says, choose the opposite.
