who is it?

[carrie]

nostromo please give me the answer i am going nuts i have no patience

[brizzle]

Got it (and a nice piece of A4 with all the permutations in front of me ).

Michael can not tell so the only combination it can't be is two reds in front of him or he would know he is green.
Tina also knows this so, discounting the fact that they are both not red, the hat on her head and Davids can either be a combination of :

David G Tina G
David G Tina R
David R Tina G

Tina can not answer because she see's green in front of her so she could still be red or green. If it was red then she would know she is green.

David knows by Tina's non-answer that he has a green hat on.

Start of with 1 and 2 going across......send 1 back and give flashlight to 10 and 5. They go across and give torch to 2. 2 comes back and 1 tags along for the return.

2+1+10+2+2=17mins!

numbers refer to the time they take to walk across

Perfect! Carrie, there is the answer. Brizzle, you get 10 out of 10.

[brizzle]

This is one of my faves :

On a wall are 3 standard on/off switches.
One (and only one) controls a light bulb inside a light-tight, well-insulated closet.
The other two switches do nothing.
You can only open the closet door once, and cannot touch/change any switches after the door is open (or re-closed, for that matter).
Damaging or disassembling the door, walls, or switches is against the rules.

Within these constraints, can you determine with certainty which switch controls the light bulb?

Told this in a bar in Eivissa by a Des Lynham lookalike....

OK. Turn on the first switch and leave it on for 10 mins at least. The switch it off and turn on the second switch. Open the closet door immediatly and touch the bulb (if it is off).

1. If the bulb is off but warm - it is the first switch.

2. If the bulb is on - it is the second switch.

3. If the bulb is off and cold - it is the 3rd switch.

Very clever, I didn't have a clue on that one. Did you figure it out Nostromo or had you heard it before?

"1st man says, you will have to guess i will give you a clue.
"Brothers and sisters i have none, but this mansfather is my fathers son,"


"so if he is holding a pic of a man who has no siblings and the man in the picture is the 1st mans fathers son.
does that make sense?"

Still doesnt to me Carrie I'm afraid.

The man holding the photo gave the clue as "brothers and sisters have I none" referring to himself (not the person in the photo) so he is an only child.

"but THIS MANS father is MY fathers son" Since he doesn't have brothers and sisters he is the only person who could be his fathers son so he must be the father of the man in the photo i.e the photo is of his son not himself.

From carrie about first riddle:
"sorry steve misread nostromos reply the picture is of himself.
brothers and sisters i have none(the man) but this mans(The picture) father is my fathers (The 1st man) Son.

so if he is holding a pic of a man who has no siblings and the man in the picture is the 1st mans fathers son.
does that make sense?"

The answer is his son, not himself. Imagine a man called Bob who has a son called John and a father called Dave. Bob has no siblings. So he can say "brothers and sisters I have none. But this man (John)'s father (Bob) is my father's (Dave's) son (Bob)". Put sort of mathematically John's father = Dave's son or grandson's father = grandad's son. The 'this man' refers to the man in the photo who is the grandson.

I swear that I had never heard of this or anything similar before. I am ususally OK with riddles.
