Ahh you helped me figure it out.

Don't think in terms of inches when it comes to the flea, think in terms of percentage of the rubber band covered.

If the flea is half way to the kangaroo (50% of the rubber band), and the kangaroo jumps a mile, the rubber band stretches, but the flea remains at 50%.
So yes, the flea will eventually catch the kangaroo.

Yeah, if X is 1 inch converted into miles, the first jump is X/100 % of the rubber band. The second jump is X/200 % of the rubber band etc...

The infinite series of

X/100+X/200+X/300+X/400 etc... assuming X is not zero or negative will go to positive infinity so given an infinite number of jumps he will traverse to 100% of the rubber band.

sorry its a good one
Ive solved it before my roomate tried and only missed barely

I tried this last night and couldn't get it, I messed up somewhere.

I did it again today and got it without too much trouble. And yes, the German.
I liked that one a lot, it makes time go by fast!

Am I stupid or does it not say anywhere in 1-15 that anyone owns a fish. I see cats, horse, dog, and bird. I'm assuming the 5th pet is an armadillo and there is no fish.

[QED]

Here's a new one I came up with.

Aldo runs a business called Aldo's Used Books, which (suprisingly) sells used books.

Every book Aldo sells is one-of-a-kind, so every book is priced differently. The cheapest book is one cent.
Aldo believes in saving paper, so on his receipts he doesn't show individual books or their sales price-- he only prints the total sales amount. Strangely, this is enough information for Aldo to know exactly what books have been sold.

Given this information, what is the maximum number of books you can buy at Aldo's for exactly $295.24?

It's been too long since math classes...
It seems like you could do hit or miss with (n)!. Or is it !(x). Hmm.. I can't even remember.

Just a ballpark guess, 242. Probably off since I'm not going to figure out the exact prices of books to come up to $295.24.

Imagine a giant kangaroo, whose tail is attached to a stake in the ground by a giant rubber band. A tiny flea is sitting on the stake.

The giant kangaroo see the flea and is spooked. He jumps and lands a mile away from the stake (to which it is still attached by the giant rubber band). The flea begins pursuit, hopping onto the rubber band, and lands one inch away from the stake. The kangaroo again jumps another mile away from the stake. The flea jumps another inch along the rubber band. This continues indefinately.

Assuming the earth is flat and infinite, does the flea ever catch up with the kangaroo?

Is the rubber band infinitely elastic?

Yes. And the flea and kangaroo live infintely long.

Yes. Infinity ~ Infinity

 

[QED]

242 would be the answer if book #1 was one cent, book #2 was two cents, book #3 was 3 cents, etc.

However, if those were the prices Aldo wouldn't be able to tell the difference between the sale of book #3 at three cents, or the sales of book #1 and #2 for a total of three cents.

i think you have to go like - 1 cent, 2 cents, 4 cents, 16 cents, 32 cents, etc...

*** Shortest among the Tallest OR Tallest among the Shortest ***

Army people are standing in the form of a matrix with 'n' rows and 'm' columns, with a total of 'nm' people.

The tallest person from each row is taken and the shortest person among these 'n' tallest persons is named A.

They are again asked to stand exactly as before.

This time, the shortest person from each column is taken and the tallest person among these 'm' shortest persons is named B.

Note: first time it is by row, second time it is by column.

Given that no two persons are of the same height, who will be taller - A or B.

If one of the faces of a tetrahedron of side 'a' is glued to one of the triangular faces of an equilateral pyramid of side 'a', then how many faces will the resulting solid have?

Well then it's just a binary arithmatic question so with that it would be 14 books (13 follow the pricing of .01*2^x while the last one would be 295.24-sum(.01*2^n,n,0,13).

just convert 29524 to binary (= 111001101010100), and count the no. of 1s.

answer is 8 as posted by yosuke188.

Whoops, refine my answer to 13 books after checking for uniqueness.

That's a better answer (8 books, not my answer of 13). I wanted to play around with the assumptions of the problem. I'm assuming that he can still deter away from the binary pricing case. So if a customer buys all the books he can in increasing price, he can buy 12 books for $163.81 (by excluding the price of 2 cents) . So the last book is some arbitrary book that costs $131.43. This can work for specific cases where Aldo leaves gaps in the pricing of his books.

$163.81 is the sum of all the books priced from 1 cent to 2^14 cents excluding 2 cents. But if Aldo does not have a book that costs 2 cents or 2^15 cents, then there will not be any ambiguity for the books here because the leading order term in the binary conversion of 29524 is 2^15 and the binary equivalent of $131.43 would require binary prices that have already been used and it would require a book that costs 2 cents if reconstructed via summation of binary prices. So without the book that costs 2 cents, then Aldo cannot reproduce the price of $131.43. And without the book that costs 2^15 cents, Aldo cannot reproduce the price of $295.24 via binary pricing either.
