    B 36 sec Correct Answer Incorrect Answer
    C 48 sec Correct Answer Incorrect Answer
    D 60 sec Correct Answer Incorrect Answer

    Solution

    Relative speed = 50 + 40 = 90 km/hrs Time taken to meet for the first time = length of the track/ relative speed => 900 / (50 + 40) => (900 x 18)/(90 x 5) = 36 sec
