68.The power fuse.



                          Arun was studying in his room.  He had put lights in every room.  Suddenly, when he was about to open his Maths book, there was a fuse in his room.  So, Arun, angrily went and bought one new bulb to replace it in the old one's  place.  He turned off his room's light switch.  He turned off every light in rooms which he was not using.  Arun carefully removed the broken bulb and replaced the new one in its place.  Then he switched on the light switch in his room.  Luckily, the light shone brightly.  So, Arun was able to study.
