1) Only two boxes were placed between the box with 16 chocolates and Cadbury, where neither of them is placed at the topmost or the bottommost positions. Campco was placed in the box immediately above the box with 16 chocolates. 3) The box with Nestle has neither 20 nor 32 chocolates. The box with Amul has more number of chocolates than Snickers. 4) The box with Campco has less number of chocolates than Cadbury but not kept below Cadbury. Hence, case 2 gets eliminated.
