Q. Because cigars cannot be entirely smoked, a hobo who collects cigar butts can make a cigar to smoke out of every 5 butts that he finds. Today, he has collected 25 cigar butts. How many cigars will he be able to smoke? 






Ans. 6, he makes 5 originals from the 25 butts he found, and after he smokes them he has 5 butts left for another cigar.
