Next thing you remember was that you were lying on your bed with normal clothes. And on the table, there lay the novel you had finished, the story of Twin dwarfs of Greeza. Indeed! You were in Greeza. Those two dwarfs at the centre of the council were the twin dwarfs. You knew about them as you had read about them. That's why they chose you. Is there any connection to their planet using the book? You started searching the book, when you saw the time in your watch. It was 01:00 pm. How much time did it take for you to reach back to Earth form Greeza (When you left Greeza, it was 02:00 pm by your watch)?
23 hours
After 12 hours of time in am, we will get the same time in pm. Similarly, after 24 hours, time will repeat. If you take the watch, cut its boundary and put it on a plane surface, you will get something like this line.
If you try to write it in integer representation, it would look like this:
The integer corresponding to 02:00 pm is 2. The integer corresponding to 01:00 pm after 02:00 pm is 25. Number of hours taken = 25 - 2 = 23 hours.
And you continued to look for anything in the book and suddenly you saw the figure of the same place where you were sitting with all the council members. Nice trip it was, wasn't it?? Thinking about that, you slept again.
