You bet. I had been staring for 20 minutes to this stupid question, but still hadn't found the answer. As I am an engineer I was thinking more about the physical aspects of time. That makes you a linguistic, right?

Yeah (well, a lawyer), also dyslexic which really helps with that kind of thing (but just try asking me to spell!)

A king lives in a castle at the top of a hill. One day he calls in his wise man (you should bear in mind that he is a wise man.)

The king says - I have 3 daughters, how old are they?

King - If you multiply their ages together the answer is 36.

King - If you add their ages together the answer comes to the number of the house opposite.

The wise man looks out of the windown, pauses and then replies - I need more information.

King - My eldest daughter is blonde.

Wise man replies - Sire, I have the answer.

How old are they?

9, 2, 2

?

multiple of 36, factorisation that has the sum of another, adds up to 13, there *is* an older daughter...

EDIT: lol, Kaiser, ur too quick *angry* lol

Maybe not! But can you explain why these ages were arrived at? And how do they fit the requirements of adding up to the number of the house opposite?

I'm guessing it's because the castle is number 1, obviously, so the opposite castle is number 2. However, that doesn't match my figures, so it must be written in Roman numerals.
I.E the kings castle = I
opposite house ( which is really 2) = II (which looks like 11?)

Well, there's my guess.

multiple of 36, one number is doubled, there *is* an older daughter...

EDIT: lol, Kaiser, ur too quick *angry* lol
Lol, sorry! yeah your're right though, each clue needs to eliminate something so he 'needs more information', the house number question means there must be two multiples that add up to the same (9,2,2 and 6,6,1) but only 2,2,9 works as the fact there needs to be an oldest daughter eliminates the other option

I thought that the 2nd clue basically told you that the number of the house oppositie, was not enough information to tell you the answer, hence it had to have a sum that was the same as another factorisation of the number 36

EDIT: lol - and too quick AGAIN - you're a sneaky one

So what is the number of the opposite house then?

lol, psychic powers above par this morning

Heres a tricky one that people might have heard before: three friends that was staying in a hotel got to check out, and pay 30 pounds. However, the receptionist then finds that a mistake has been made, as the room only cost 25 pounds. She can't work out how much each is owed of the 5 pound differance, and so gives them one pound back each and keeps the other 2 for herself. But this only makes 29 pounds in total that have been accounted for, 9 for each friend and 2 for the receptionist, where has the other pound gone?

I guess it would be 13, but thats not important to the question the important thing is that theres two possible combinations to reach that number so another question is needed.

I was fooled by the castle bit as well (was wondering if there was another hill nearby or something ) particualrly after the previous question, but this one is straight maths/logic)

no, because that would mean the house opposite was number 11, therefore, the wise man wouldn't need any more information to know the ages of the three duaghtyers, only because the sum - 13 has two solutions means that he needs one more clue - that there is an eldest daughter.

Kaiser

the final statement is a trick really? the £9 each friend is paid INCLUDES the 2 pounds the receptionist made. the remaining pound out of ten was returned to each. (Hotel's 25 plus receptionists 2 plus each friends 1 equals 30. )
In the end they paid £27, £25 to the hotel and £2 to the receptionist, the other £3 are in their pockets, 27+3 = 30. The final line of the puzzle is a misdirection.

Yeah well done! Took a very long time for me/other people to figure that out....
