Practice Test Discussion


If two pipes A and B can fill a tank in t min. If time taken by A alone is 4 minutes more than t and time taken by B alone is 25 minutes more than t, then the time taken by both the pipes together is?

  • Explanation

    According to the above given formula, Two pipes A and B can together fill a tank in time T. If time taken by pipe A alone is more than T by x and the time taken by pipe B alone is more than T by y, then T is xy min.

    So, T=4×25=100=10 min

    The tank will be completely filled in 10 min.

    Hence option C is correct
