Question : Directions: If 5 November 2019 was Tuesday, then what was the day of the week on 5 December 2011?
Option 1: Tuesday
Option 2: Sunday
Option 3: Monday
Option 4: Saturday
Correct Answer: Monday
Solution :
Given:
5 November 2019 was Tuesday.
The number of days from 5 December 2011 to 31 December 2011 = 26
The number of days from 1 January 2012 to 31 December 2018 = 366 + 365 + 365 + 365 + 366 + 365 + 365 = 2557
The number of days from 1 January 2019 to 5 November 2019 = 309
So, the total number of days = 26 + 2557 + 309 = 2892
Now, divide 2892 by 7 to get the odd number of odd days.
Number of odd days = 2892 ÷ 7 = 1 (remainder)
5 November 2019 was Tuesday.
Thus, 5 December 2011 = Tuesday – 1 = Monday
So, Monday was the day of the week on the 5 December 2011. Hence, the third option is correct.
