    16) We have: 

    SOLUTION 1

    8 + 1 + 3 = 12; 1 + 2 = 3

    9 + 0 + 9 = 18; 1 + 8 = 9

    4 + 5 + 3 = 12; 1 + 2 = 3

    So 1 + 4 + 6 + 2 = 13; 1 + 3 = 4.

    SOLUTION 2

    8 + 1 + 3 = 12; 12 - 9 = 3

    9 + 0 + 9 = 18; 18 - 9 = 9

    4 + 5 + 3 = 12; 12 - 9 = 3

    So 1 + 4 + 6 + 2 = 13; 13 - 9 = 4

    ANSWER: 4

    15) If John took the chocolate => Only Wendy told the truth => SATISFY

          If Wendy took the chocolate => John, Charlies and Sally told the truth => UNSATISFY

          If Charlies took the chocolate => John and Charlies told the truth => UNSATISFY

          If Sally took the chocolate => John and Charlies told the truth => UNSATISFY

    So John took the chocolate.
