If these are all logical people doing logical things, wouldn’t they just ask “What color is my eyes” and everybody leaves on Day 1?

Still wrong.

THE BROWN EYED PEOPLE CAN NEVER LEAVE.

EVER.

1. Day, all blue-eyed people leave.
2. Day, all brown-eyed people leave.
3. Guru leaves when all other people are gone, because of the fact that she is a guru.

Um, still no. The guru and the brown eyed people … how could they ever deduce their own eye color? How would the guru know that her eyes are green not purple?

solution was based on the fact that when the guru sees all the people preparing to leave it’s bound to know he has a different eye color

Answer you probably wanted:
On day 100 – all people with blue eyes leave
On day 101 – all people with brown eyes leave
On day 102 – guru leaves

Your first statement is correct, but your second … isn’t. How would the guru and the brown eyed people ever know their own eye color?

On day 100 – all people with blue eyes leave
On day 101 – guru and people with brown eyes leave

If anyone would like a hint… try using smaller numbers and see what would happen logically.
