Numericals

I just came to know that empty beer bottles fetch you Rs 2.50 each. That means if I can collect 20 beer bottles, it would fetch me a cool Rs. 50 note. Hmm – so if I buy 20 beer bottles, it would mean that the 21st one comes absolutely free, plus I may get another free cause of bulk purchase… How cool is that? If only such offers were there in examinations… You answer 20 questions and the marks for 21st one is absolutely free, without any effort of yours.. sigh!! if only this analogy worked….
