Correct Answer - Option 1 : Monday
12 May 2011 = Thursday
Number of years between 2004 and 2011 = 7
Number of leap years between 2004 and 2011 = 1
So, total number of odd days = (7 + 1)/7 = 8/7 = 1 (remainder)
As, 12 may 2011 = Thursday
So, 12 May 2004 = Wednesday (Decrease 1 day as 1 odd day)
So, 10 May 2004 = Monday
Hence, "Monday" is the correct answer.
