If 5 November 2019 was Tuesday, then what was the day of the week on 5 December 2011?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Monday
5 Dec 2011 - 31 Dec 2011 = 26 days
No. of odd days in 26 days = 5 days
No. of odd days from 1 Jan 2012 to 31 Dec 2018 = 2 + 1 + 1 + 1 + 2 + 1 + 1 = 9 odd days
No. of odd days from 1 Jan 2019 to 31 October 2019 = 3 + 0 + 3 + 2 + 3 + 2 + 3 + 3 + 2 + 3 = 24 = 3 odd days
No. of odd days from 1 November to 5 November 2019 = 5 odd days
Total number of odd days = 5 + 9 + 3 + 5 = 22 days = 1 odd day
Day on 5 December 2011 = Tuesday - 1 = Monday
Hence, the correct answer is Monday
