Riddle: There is a certain club which is for men only. There are 600 men who belong to this club and 5 percent of these men wear one earring. Of the other 95 percent membership, half wear two earrings and the other half wear none. How many earrings are being worn in this club?
Answer: Six hundred. We know that 5 percent, or 30 of the men are wearing one earring. Of the other 95 percent, or 570, we know that half are wearing two earrings and the other half none. This is the same as if they all wore one.
