Eight persons — A, B, C, D, E, F, G, and H — bought different items: lamp, calculator, pen, pencil, book, watch, bag, and laptop, one after another, not necessarily in this order. A bought an item immediately after C. Three persons bought items between C and the person who bought the pen. Three persons bought items between the person who bought the pen and the person who bought the calculator. G bought an item immediately before the person who bought the calculator. The number of persons who bought items before the person who bought the calculator is the same as the number of persons who bought items after the person who bought the watch. G does not buy the watch. H bought the laptop immediately before E and immediately after D. Two persons bought items between D and the person who bought the bag. G does not buy the lamp. B bought an item before F. G and D do not buy the book. How many persons bought items after the person who bought the lamp?

  1. Four
  2. Three
  3. Five
  4. Two

Correct answer: Five

Solution

The clues force a unique order of persons and item assignments. After arranging all eight persons and matching the items, the lamp is found at the 3rd position from the start. Therefore, five persons are after the person who bought the lamp.
