I have a number of roses for sale. The first buyer bought half of my roses then I gave him additional one for free. The second buyer bought half of the remaining roses then I gave him additional one also for free. The third buyer also bought half of the remaining roses then I gave him additional one also for free, this time all of my roses has been sold out.
How many roses do I have?
0 you sold them all! ???

First person: 1/2 +1 gave one away
2nd Person: 1/2 of a 1/2 (1/4) +1 gave one away
3rd Person: 1/2 of a 1/2 of a 1/2 (1/8) +1 gave one away
so 1/8th = 3 (that's how many he gave away)
3 x 8 = 24

5 1/2 is half of 11, not 14.
The answer can't be 14. If that was the case than the first person would buy 5 1/2. How can you buy a half. If they want the beginning amount then the correct answer is 24.
24 won't work because then you will run into a situation where the second buyer buys 5 1/2 roses. If selling fractions of roses is legitimate, the seller could never end up with 0 roses. Starting with 24, the seller would be left with 1 1/4.
