Brown bottles puzzle on Investigation 3
Do the following to solve the puzzle:
Fourth minus third bottles is 21. Third minus fifth bottles is 10. First minus fourth bottles is 14. Second minus first bottles is 4. Fifth minus second bottles is 7. Bottles: 22, 1, 19, 12, 15. 22  12 = 10, therefore bottle 3 is 22 and bottle 5 is 12. If bottle 5 is 12, then 12x = 7. 12  19 = 7, therefore bottle 2 is 19. If bottle 2 is 19, then 19x = 4. 19  15 = 4, therefore bottle 1 is 15, leaving only one number that could be bottle 4 Chronicle Office.
