Think lateral. No math skills required.

QN?

Although if it is QN, I would have made the series:

PN KT BP RK QN KG

So maybe I am imagining things....

[CyberGnu]

Yep

I think the QN makes it too easy...

Your turn!

[Rogan Josh]

Hmm... How about:

P is to L.
M is to OK.

Hence:

D is to ??


That one is a bit hard (for me at least), so I will give you an easy one to give you a sense of acomplishment :

Bob's next door neighbour is 45 years older than him. Also the two digits in Bob's age, both prime, are the reverse of the two in his neighbour's age. How old is Bob?

[Urban Ranger]

27

[Rogan Josh]

Well done (It only took him 3 minutes! humph! )

What about the other one?

[CyberGnu]

Beats me...

[Rogan Josh]

OK - I don't think anyone is going to get this, so...

P is to L -> pistol
M is to OK -> mistook
D is to ?? -> distort (it is the only one I can think of anyway)

so the answer is 'RT'.

Urban Ranger's turn now since he got the easy one.

Cool! My turn again.

There is this question, when you ask it to a person who can answer it, the answer is always no. Anybody who is going to answer yes, will not be able to answer it.

What is this question?

Are you Dead???

[Urban Ranger]

Hm, I suppose that is acceptable.

Your turn to pose a question.

Or
Are you Dumb? Which works on so many different levels.

lol
ok then here's a classic and a tough one. Think it through before answering.


Imagine there are four Designs in front of you;

A red triangle, blue triangle, red circle and blue circle.

I have written down one of the colours (red/blue) and one of the shapes (triangle/circle).

If, and only if, any of the designs includes either the colour I have written down, or the shape I have written down, but not both, then it is called a GOHT.

I will tell you that the red triangle is a GOHT.

Each of the remaining designs can now be classified into one of the following categories.

A: Definately is a GOHT
B: Not enough information to decide
C: Definately is not a GOHT

Which designs go into which categories?

[Rogan Josh]

Let me try:

red triangle: A (obviously!)
blue cirle: A (since we know either red or triangle is correct but not both the smae must be true for blue and cirlce)
red circle: B (since it could be both or only red)
blue triangle: B (since it could be both or only traingle)

[rah]

red triangle, A
blue triangle, C
red circle, C
blue circle, A

Since the only two combinations you could have picked are
red/circle or blue/triangle.
