Hey..!!

Harihar opened the pipes A and B to fill an empty tank and some times later he closed the taps A and B , when the tank was supposed to befull.

After that it was found that the tank was emptied in 2.5 hours because an outlet pipe "C" connected to the tank was open from thebeginning.

If Harihar closed the pipe C instead of closing pipes A and B the remaining tank would have been filled in
