Once there was a king. He was upset because thieves kept stealing costly jewels from his locker. Here is what the locker looked like:
The locker could be opened by giving its handle half a turn. Another half turn and the locker would be locked again.
- The king would often leave the locker open thinking it was locked. Can you guess the reason?
उत्तर
It the looks same in both positions. Hence, the king often gets confused and cannot tell if it is locked or open.
