Question 3:
Some parrots were sitting on two telephone-lines. One of the parrots on the first line said to those on the second: 'If one of you come over to us, we will be twice as many as you.' A parrot on the second line replied: 'If one of you come over to us, there will be the same amount on both lines'. How many parrots sat on the first line?

7 and 5

Question 5:
Yesterday I met an old friend that I hadn't seen for many years. He told me that he had 3 children, and when I asked how old they were, he said that the sum of their ages is 13, and if you multiply their ages, the result is the same as your own age. I knew my own age, of course, but I still could not tell how old his children were, so he had to give me another hint. He then told me that the oldest one was visiting his grandparents right now. How old was this child?

Was the oldest child 9 with the others both being 2 years old?

Um, can you explain the reasoning behind this one? Thanks.

I used Excel to simplify it for me, but here's how to start.

Write down all combinations for the 3 ages that add up to 13 and figure out what the product of the three would be. Listing the youngest kid first, the table looks something like this:

1 x 1 x 11 = 11
1 x 2 x 10 = 20
1 x 3 x 9 = 27

Keep doing that until you get all combinations (make sure you don't double count any combinations, like 2x4x7 and 4x2x7).

Here's the important part - the information provided in the first part wasn't enough to tell him the ages of the kids. That means that whatever age he is must have had more than one combination. The only product that appears twice is 36 (2x2x9 and 1x6x6).

Now, since he mentioned the oldest child you know that there is a singular oldest kid. Therefore, the 1x6x6 is out.

That leaves 2x2x9 as the only valid combination.
 
the answer too mine were
#3, ride each other's horse, that way if you come in first your horse came in last and you win and get to marrie the princes

#4. the princess writes a letter and puts it in a box and locks it, now only she has the key so how does the prince get ther letter?
the guard brings him the locked box, and he puts on a second lock that only he has a key to, the box goes back to the princess where she takes off herlock, then the box returns to the prince, now he can take off his lock and get the letter out.
see now wasn't that simple lol.

This is the answer given from the site where I got these...

The number of children he has is 1 based on the following logic :

Look at the vowels in their names. A=0, E=1, I=2, O=3, U=4, Y=0

Wow... it would have taken me quite a while to figure that one out.
 
That's too much work to get a letter. Never would have thought of that one Fly.

I was on the right track with the with number 10, but I was only looking at the first letter of each name. Doh!

I will try to answer some of them today, yesterday I didn't have enough free time to do any of them.
 
My guess for #7 is that the number is: 6210001000

you got:
6 zero's
2 one's
1 two
1 six


is that right?

Ok Bratcat, I am stumped on the last 3.
