Where in the World.

(A survey this week found one in five British children could not find the UK on a map of the world. What about other countries? Test yourself by identifying the 10 countries highlighted in the following questions).
It's not hard, I managed to correctly answer 4 / 10!!!

Given to me by a fellow, who has challenged the membership to arrive at the correct answer. I - of course - told him that we would probably have many peoplewritingin, as I am aware that amny of you have a math background.

SO

I have $1000 in Loonies, and 10 empty bags. How must I divide the money into the bags so that no matter which amount that you ask me for, I can reach for the appropriate bag or bags immediately?

Answers to me please

(The poser figures that nobody will get the correct answer, I told him rubbish!!)

OK I think I got it now (2 1/2 hours)
The solution is there will be 12 solutions with last numbers ranging from 489 to 500
The first 6 numbers 1,2,4,8,16,32 will always stay the same. Mike Doyle.

It's an easy one. You set it up as if each bag were a binary digit: 1, 2, 4, 8, etc.., except that in your last bag you run out of loonies so you have to put in just 489 loonies instead of the full 512 that would be the normal value of the left-most digit in a 10-digit binary number. You can tell your friend that I had it solved before I'd finished reading the question ;)

Answers to "What number comes next!

The first letter in the words "one", "two", "three", "four", etc... so next letter is "S" for "Six".

The first letter of every second month: February, April, June, August, ... so next letter is "O" for "October".

Each line is a description of the line above it. Line #2 is to be read as "there is one number 1". line #3 should be read as "there are two of the number 1". line #4 should read "there is one number 2, and one number 1", etc... so the next line should read "13112221" and should read as "there is one number 3, one number 1, two number 2s, two number 1s".

They are all representations of the decimal number "ten", writen in decreasing bases. "10" is base 10 (decimal). "11" is base 9, "12" is base 8, "13" is base 7, etc... so the next number is base 2 (binary) and should be written as "1010".
