    Set 1

    The six members of the Justice League were ranked by a group of friends – Leonard, Sheldon, Raj and Howard. From every friend, each character received a distinct integral rating ranging from 1 to 6, depending on how much the character was liked by that friend, i.e. the character he liked most, was given a rating of 6 and the character he liked least was given a rating of 1 and so on. The six characters were named Batman, Superman, Wonder Woman, Aquaman, Cyborg and Flash.

    Further information is given below:
    I. Batman received a different rating from each friend. This holds true for the other five characters as well.
    II. For each of Batman, Wonder Woman and Cyborg the ratings received from the four friends were in A.P.
    III. The sums of four ratings received by Batman, Wonder Woman and Cyborg were also in A.P., with a common difference of 4, not necessarily in that order.
    IV. The sums of four ratings received by Superman, Aquaman and Flash were also in A.P., with a common difference of 1, not necessarily in that order.
    V. The ratings received by Batman from Sheldon, Wonder Woman from Howard and Cyborg from Raj were the same.
