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.

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.

Oo nice.
