    The speed of Bangalore-Mysore train is TWICE the speed of Mysore-Bangalore train.

    EXPLANATION-

    Let the time required to reach the meeting point is t
    Speed of Bangalore-Mysore train be U
    Speed of Mysore-Bangalore train be V
    So,
    The meeting point would be at a distance of u*t and v*t from the two stations.
    Now according to the given condition
    u*t = v*4
    and
    v*t = u*1
    on taking the ratio of these 2 equations,
    we have,
    u/v = 4v/u
    u/v = 2/1

    Hence, the speed of Bangalore-Mysore train is TWICE the speed of Mysore-Bangalore train.
