    Question

    Anshul lives on 15th floor and Keshav lives on 55th

    floor. Anshul goes up at a rate of 36 floors per minute and Keshav comes down at a rate of 44 floors per minute. At which floor they will meet? 
    A 38th Correct Answer Incorrect Answer
    B 26th Correct Answer Incorrect Answer
    C 32nd Correct Answer Incorrect Answer
    D 33rd Correct Answer Incorrect Answer

    Solution

    Total floors between Anshul and Keshav = 55 – 15 = 40 floors Relative speed = 36 + 44 = 80 floor/min Time taken by them to meet = total floors/relative speed = 40/80 = 1/2 min Anshul travels in 1/2 min = 1/2 x 36 = 18 floors Floor at which Anshul and Keshav will meet = 15 + 18 = 33rd floor
