Problem of the day 7/14/11

   One full box of candies weighs 1.59 kg. If I take out 40 candies from the box, the weight of the box comes down to 1.47 kg. How many candies are there in the box originally? (Ignore the weight of the box that holds the candies)

	120 candies
	450 candies
	530 candies
	340 candies
Answer: 530 candies. Explanation: The weight of 40 candies must be 1.59 - 1.47 = 0.12 kg = 120 grams. So, each candy must weigh 3 grams. The original weight of the box was 1.59 kg = 1590 grams. Number of candies = 1590/3 = 530 candies.
