PUZZLE-MIND WORKOUT

Hai guys,

From today, i took a decision every Sunday i will post puzzles or quizzes.

So, today the puzzle is "100 doors".

Solution for this puzzle will reveal in next Sunday.

You guys try yourself don't google it. OK! Guys!...

Lets we move on to today's puzzle.

Imagine you are standing in front of 100 doors.

Every time you toggle the door while you cross the doors.

Example: if the door open means you will close the door then if the door closes means you will open the door.

Initially, all the doors are closed.

So you walk 100 times across every door in the following manner:

In the first walk toggle the door in multiple of 1, which means

In the second walk toggle the door in multiple of 2, which means

then the third walk toggle the door in multiple of 3, that means

3,6,9 and so on. In this fashion, you walk for 100 times.

So the puzzle is "WHAT ALL ARE THE DOOR NUMBERS WILL REMAIN OPEN AFTER HUNDREDTH WALK"

IMPORTANT NOTE: "INITIALLY ALL THE DOORS ARE CLOSED"

OK, GUYS!TRY IT OUT...
