Answer / guest
The tank will be full in 16 minutes.
In one minute,
pipe A can fill 1/30 part of the tank.
pipe B can fill 1/24 part of the tank.
pipe C can empty 1/80 part of the tank.
Thus, the net water level in one minute is
= 1/30 + 1/24 - 1/80
= 15/240 part of the tank
Hence, the tank will be full in 240/15 i.e. 16 minutes.

Answer / mithilesh.patidar
obviasly 16 minutes.............b'cas
in 1 minute a can fill the tank=1/30
in 1 minute b can fill the tank=1/24
then both fill the tank in 1 minute=1/30+1/24
=54/30*24
=3/40
c can empty the tank in 1 minute=1/80
then pipe will fill in=3/40-1/80
=1/16
hence
for fill the full tank it takes 16 minutes....

In a kingdom far far away, the King decided that the time has come to find a husband for his princess daughter. The King wanted to find a worthy lad for his princess, so he promised to give his daughter away to the first young (or old) man who would solve the puzzle that has stumped the best of his court mathematicians for years. The puzzle is very simple: in a palace, there are 25 rooms arranged in a square--5 rows of rooms with 5 rooms in each row. In every room there is a light switch which not only switches on/off the light in that room, but also switches the lights in the adjacent rooms--the room to the right, to the left, the room above and the room below. Initially, all of the lights are turned off. The goal is to turn the lights on in every room of the palace.
