If 25 October 2004 was Monday, then what was the day of the week on 2 November 2007?

Correct option is A

Given:
25 October 2004 was Monday.
From 25 October 2004 to 25 October 2007, there are 3 odd days.
(3 odd days of 3 normal years.)
Now, add the odd days to the given day of week:
Monday + 3 = Thursday (Tuesday, Wednesday, Thursday)
So, 25 October 2007 was Thursday.
So, now, the number of odd days from 25 October 2007 to 2 November 2007 = 1
Thus, 2 November 2007 → Thursday + 1 = Friday.
