What was the day of the week on 24th October 2011?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Monday.
24th October 2011 = 2000 years + 10 years + 1 Jan 2011 to 24 October 2011
No. of odd days = 2000 years = 0 odd days
10 years = 2 leap years (= 4 odd days) + 8 ordinary years (= 1 odd days) = 4 + 1 = 5 odd days
(Ordinary year = 365 ÷ 7 = 52 weeks + 1 odd day, Leap year = 366 ÷ 7 = 52 weeks + 2 odd day)
1 Jan 2011 to 24 Oct 2011 = 297 days = 3 odd days
Total = 0 + 5 + 3 = 8 = 1 week and 1 odd days
1 is the code for Monday.
