ur question is little bit wrong ..bcz inlet pipe is taking much time than outlet pipe..means the capacity of inlet is more than outlet ..therefore if tank is empty than it is not possible to fill bcz when inlet pipe fills 4 unit outlet pipe will empty it 5 unit.. i hope u understand the fact
it will not be full at all
