Gemarific!!


You have 5 bags of gems each containing 10 gems. All gems have the same shape and size. Each gem weighs 10 grams so a bag weighs 100 grams. But there is a bag of gem that contains gems with 9 grams (bag weighs 90 grams). You have a weighing scale that can register a maximum of 200 grams. What is the least number of times you could use the scale to find the bag with 9g gems?
