    The Family Murder Riddle

    Hint:
    We know from (3) that the youngest person was not the victim, from (4) that the youngest person was not the helper and from (6) that the youngest person was not the killer. The youngest person can only have been the witness therefore. If we make up a chart there are now three possible combinations:

    Oldest person (father) H H M

    Next to oldest (mother) V M H

    Next to youngest (son) M V V

    Youngest (daughter) W W W

    (H = Helper ; V = Victim ; M = Murderer ; W = Witness)

    We can work out from (5) that the father was the oldest, from (2) that the youngest person must have been the daughter. Therefore the next to the youngest must have been the son and the next to the oldest, the mother.

    Of three possibilities: the first is impossible (from (3) the youngest person and the victim were of different sexes); the third is also impossible (from (1) the witness and the helper were of different sexes). Therefore only the second possibility holds and the mother was the murderess

    Digits From 1 To 9 Riddle

    Hint:
    A = 7
    B = 1
    C = 9

    D = 8
    E = 4
    F = 5

    A + B + C = 17
    D + E + F = 17
    B2 + B + F = A
    C × F = EF

    To begin with, B has to be a 1 or 2 or else A wouldnt be a single digit. Plug in B = 2, gives you 6 + F = A, meaning F and A can only be (1,7) or (3,9). To get 17, C would have to be 8 or 6, but those values dont work for C × F = EF. So B must be 1.

    2 + F = A means F and A can be (2,4), (3,5), (4,6), (5,7), (6,8) or (7,9). To get 17 on the top row, the only option that leaves C as a single digit is F = 5 and A = 7.

    C × F = EF
    9 × 5 = 45, so E = 4 and D = 8 to make the second row equal to 17.
