Anna’s picture

Once upon a time there was a beautiful princess named Anna. Anna's father, the King, wanted to be sure his daughter married an intelligent man. To test his daughter's suitors the King hid Anna's picture in one of three boxes. The suitor had to be able to select the box with Anna's picture on one try and within twenty seconds.

On the gold box was the message "Anna's picture is in this box". The silver box had the message "Anna's picture is not in this box."
"Anna's picture is not in the gold box" was written on the bronze box.

The King would tell each suitor "Only one of the three messages is correct." Which box contained Anna's picture?

The person who gets the correct answer may ask the next question.
Give it shot people!

Very Good, How did you come to that answer?
Btw, Becuase you gave the correct answer before TGO, its your turn to ask next :)

The clues are in this sentence "Only one of the three messages is correct" so there ya go.

As for the question let see:
A guy ordered a length of rope by calling to his nearest hardware store. But when got pick it up, he found that the associate had mis-written the order by interchanging feet and inches. As a result of this, the rope was only 30 percent of the length that the man wanted. What length did he want and what length did he get?

Im not sure I understand the question. He wrote the same numbers the guy wanted, but instead ft he wrote inches?

shoshy - thats right, example 5 ft 2 in, instead the associate wrote 2 ft 5 in.

good luck

Ok, I dont know if I am right, but I think the guy ordered 5 ft and 1 inch of whatever, and he got 1 ft 5 inches instead (which is 30% of what he wanted).

you are correct -- ( i think ) :)

How can that be correct? If that's correct, the question is wrong then.

5'1" = 61"
1'5" = 17"

17" is not equal to 30% of 61" (closer to 28%).

I went by your logic as well, and got the same answer as you at first. then looked at the question differently, and got my answer. So i think the question is phrased badly.

How did you look at the question that this answer makes it so that what he got was 30% of what he wanted?

The way BukharskiyParen explained it , that The customer ordered for example 5ft and 1in of material, but the worker wrote it down as 1ft and 5in. 1.5 is 30% of 5.1. I dont know if my logic is right though.....this is a confusion question.
At first I started converting it all to inches and looking at relationships, but I didnt think that was right, so I tried it this way.
i dont know :(

Shoshy let me unconfuse you by giving you the right answear, (TGO was going in the right direction)

The correct answear is:
The person ordered 9'2", but instead got 2'9"

9'2" = 110 in
2'9" = 33 in (which is 30% of 110)

So here ya go ... :)

1.5 is not 30% of 5.1, though close.

But I solved it, so look at my next post. :)

Внимание, правильный ответ (и как его получить!)! :)

9'2" = 110" -- what he wanted
2'9" = 33", which is 30% of 110", -- what he got

Here's how you can get to these numbers:

Let's say the number of feet is n . Let's say that the number of inches is k.
Then, knowing that there are 12 inches in a foot, we get the following equation that corresponds to the problem:

12n + k = 0.3 ( 12k + n)
12n + k = 3.6k + 0.3n
11.7n = 2.6k
11.7n/2.6 = k
4.5n = k
k/n = 4.5 <-- the ratio by which the # of inches ended up greater than the number of feet.

From this we see that the ratio of inches he ended up with is 4.5 greater than the number of feet. Assuming that the numbers of both feet and inches are whole and that they have to be under 12 (otherwise, you'd be able to extract a whole foot from the number of inches of >= 12), we conclude that the smaller number has to be even (for the greater number to be whole) and it has to be under 3 (otherwise, the greater number will be > 12) and the only such number is 2. Given that the ratio has to be 4.5, the second number is 9.

Hence, it's:
9'2" = 110" -- what he wanted.
2'9" = 33" = 30% of 110" -- what he got, which is 30% of what he wanted.

Hope this is all clear now. :)
