Name: jimmy Who is asking: Student Level: Secondary Question: Plz help me in detail. Help will be appreciated. Many thanks! A chemist had 8 flasks capable of holding 12, 15, 27, 35, 37, 40, 53 and 69 fluid ounces respectively. He filled some with water and then filled all the rest except one with alcohol. He used exactly one and a half times as much alcohol as water. Which flask was left empty and which were left with water and which with alcohol? Hi Jimmy,As a starter for your problem, the important clue is that the total number of fluid ounces of water and alcohol combined should be a multiple of 5 (can you see why?). There is only one flask in the lot that can be kept empty so that the capacity of the others (in fluid ounces) will be a multiple of 5. Try to find which one it is. Once you find it, you will also know the exact volume of water and the exact volume of alcohol (in fluid ounces), and from there it will be easy to assign a fluid to each flask. Cheers,Claude
