What day of the week was 29 june 2010?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e Tuesday.
29th June, 2010 = (2001-2009 years + Number of days from 1.1.2010 to 28.6.2010
Odd days in 1600 years = 0
Odd days in 400 years = 0
9 years = (2 leap years + 7 ordinary years) = (2 x 2 + 7 x 1) = 11 days → 4 odd days
Jan + Feb + March + April + May + June
(31 + 28 + 31 + 30 + 31 + 29) = 180 days
Therefore, 180 days = (25 weeks + 5 days) → 5 odd days
Total number of odd days = (0 + 0 + 4 + 5) = 9 → 9 days → 1 week + 2 odd days.
Thus, the day is Tuesday.
