  • Q11) Seven Hockey teams A, B, C, D, E, F and G participated in a tournament. Each team played with every other team twice and D won all of its games and F lost all of its games. B and G scored equal points and are ahead of C. C, A and E also scored equal number of points. Each team gets 3 points, 1 point and no point for a win, draw and loss respectively.
    What is the highest possible number of points that can be scored by team A?
    a. 14
    b. 15
    c. 16
    d. 17

  • Total number of matches = 42
    total points without draw = 42*3 = 126
    with draw point reduces by 1
    bcz win-lose - point distribution=3

    draw -draw= point distribution=2

    Let the total points of A,C,E be a and that of B and G be b
    3a + 2b + 36 = Total points [ also a< b ]
    Total points can be 126 or 125 or 124 and so on
    But our objective is to maximize a we have to take value of total as high as possible.
    3a + 2b = 126 then max = 16
    but if we take 3a + 2b = 125 then max(a) = 17
    so 17
