1. Firal Street - though "none of the three mentioned streets" also works.

Reasoning:
Options 2 and 3 are mutually exclusive therefore one is true, one is false.
Since two are true, then one of 1 & 4 is true and the other false.
If 1 is true then the club is on Kayton St. But then 4 is false, so the club is on Vilo St. This is contradictory. 1 must therefore be false and 4 true.
Therefore the club is on neither Kayton or Vilo St. If 2 is true and 3 is false, the club must be on Firal St.
Note however that 2 could be false and 3 true, in which case the club is not on any of the three streets.

I've solved the remaining questions but I'll give someone else a chance at 'em first.

Q2 B & C

If the gold is in D, then D's statement equates to "I am lying". This is inherently contradictory. Therefore D cannot have the gold.

If the gold is in A, then A's statement is false, B's true and D's true. Since two of the other three statements are true, C's statement will be contradictory regardless of truth or falsity. Therefore the gold cannot be in A.

The two boxes to open are thus B and C, and can be supported as follows:
Gold in B: A false, B false, C true, D true
Gold in C: A true, B false, C true, D false

Will post the answer to number 3 in the morning if nobody beats me to it...

j26 = 2*(j25+1)
j27 = 2*(j26+1)
= 2*([2*(j25+1)]+1)
= 4*(j25+1)+2
= 4*j25+6
but j27 = $12
thus 4*j25 + 6 = 12
j25 = 6/4 = $1.50

I seem to be playing with myself *... oh well, at least one person appreciates this quiz Mitty.

I'd give you more of a hand Psuedo but time isn't allowing me today!

Anyway, Qu 8 I think Statement C is false

6. Just statement 3 is true?

10. The gold is in C ?

9. Statement 2 is true

7. Yes.

Man 2 would always say Man 1.
Man 1 (the liar) would say either;

- Man 2 (and then Man 3 would say Man 3 to be different)
- Man 3 (and then Man 3 would say Man 1 to be different)

(unless I've totally misread that)

I reckon it's B.

We got a nerd-off situation! Adjudication please Mitty!

Dissident wrote:6. Just statement 3 is true?

If just 3 was true, then the sum of false statements would be 3, meaning 2 would have to be true also.

I reckon none of 'em is true.

A false
B false
C true
D true
