One Saturday afternoon, four boys visited the local 5 and 10 store to buy candy. Each boy bought just his favorite candy and they all had a different favorite. They each spent under one dollar and they each bought a different amount of their favorite candy. Can you determine each boy’s full name, the type and quantity of candy each boy purchased, and how much each boy spent?

  1. Peter, whose last name isn’t Smythe, bought one piece less than the boy who bought the Tootsie Rolls but he spent 15 cents more.
  2. Adam, who spent 35 cents, spent the least. The boy who bought the lollipops spent the most.
  3. Tom Wilson, who spent 10 cents more than John, spent 60 cents.
  4. The amount spent by each boy, from the least to the most, was the boy who bought the peppermints, the boy whose last name is Smythe, the boy who bought the Tootsie Rolls, and the boy whose last name is Brown.
  5. Peter’s last name isn’t Parker.
  6. The boy who bought ten gum drops, whose last name isn’t Parker, bought the largest quantity. The boy who spent the most bought the smallest quantity.
  7. The boy who got seven peppermints had two more pieces than the boy who got the lollipops.

    Answer:
    Adam Parker bought 7 peppermints at 35 cents
    John Smythe bought 10 gum drops at 50 cents
    Peter Brown bought 5 lollipops at 75 cents
    Tom Wilson bought 6 tootsie rolls at 60 cents
    Explanation:
    Let’s simplify the grid into smaller tables
    Table NO.1

    Name           Brown          Parker           Smythe           Wilson           Gum          Lolli     pepermnt     tootsie 

    Adam             —–                                                                      —–                                                           —–

    John               —–                                                                       —–                                                          —–

    Peter               Yes                  —–                —–                  —–                   —–           Y es           —–                —–

    Tom                 —–               —–                     —–                 Yes                                                          —–

    From condition 1,3&5 Peter’s last name is found out which is Brown. Peter  did not buy Tootsie rolls since he bought one piece less than the guy who bought tootsie rolls.He did not buy gum drops since they are bought in the largest quantity.  He did not buy peppermint since the guy who peppermint got two more than the guy who bought lollipop.
    Now coming to the amount spent,
    Adam – 35 cents(given)
    john-50 cents(given)
    peter-65/75
    tom-60 cents (given)
    Peter spent 15 cents more than the  guy who bought tootsie rolls. the price of tootsie rolls cannot be 35, since 50 cents was spent by john(contradicts). So, the amount spent by Peter is either 65 or 75.(He spent the most either way)
    Condition 4: Arranging them in the order of their spending
    Adam,John, Tom and Peter( use the given details in the table below)

    Name        Brown          Parker          Smythe       Wilson            Gum         Lolli        pepermnt     tootsie

    Adam         —–                 Yes                —–                —–                     —–          —–                Yes               —–

    John            —–                —–               Yes                  —–                     Yes           —–                —–               —–

    Peter          Yes                  —–              —–                 —–                     —–           Yes               —–              —–

    Tom               —–               —–               —–                Yes                        —–           —–               —–            Yes

    Condition no 6:
    10 gum drops is the largest. Peter spent the most bought the least quantity.( which is 5 lollipops).So, adam bought 7 peppermints.(condition 7)
    From condition 1, Tom bought 6 tootsie rolls.
