    The line which is part of the boundary of the area for Malaysia is a diameter,
    and a diameter divides a circle into ? equal ?

    The total area corresponds to 100%, the % for Malasia and the other

    1/4
    12.5%
    1/2, 1/8, 1/4 or 25%

    (each is liked by 1/8 of all subjects questioned)

    1)11/100
    2)50%
    3)17%
    Yes

    i)110
    ii)55
    ii)1:2
    if 500 visited M, then there were 1000 visitors altogether, so the first two
    of these should be 220 and 110 respectivly
