    A 38th Correct Answer Incorrect Answer
    B 28th Correct Answer Incorrect Answer
    C 29th Correct Answer Incorrect Answer
    D 30th Correct Answer Incorrect Answer

    Solution

    Total floors between Anshul and Keshav = 49 – 16 = 33 floors Relative speed = 28 + 38 = 66 floor/min Time taken by them to meet = total floors/relative speed = 33/66 = 1/2 min Anshul travels in 1/2 min = 1/2 x 28 = 14 floors Floor at which Anshul and Keshav will meet = 14 + 16 = 30th floor
