If 19 July 2012 is Thursday, then what will be the day of the week on 11 January 2018?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Thursday.
The number of odd days from 19 July 2012 to 11 January 2018:
19 July 2012 - 31 December 2012 = 12 July + 31 August + 30 September + 31 October + 30 November + 31 December = 165 ÷ 7 = 4
2013 - 2017 → Full years (4 Ordinary years + 1 Leap years) → (1 odd day × 4 Ordinary years) + (2 odd days × 1 Leap years) = 6 odd days
1st January 2018 - 11 January 2018 = 11 ÷ 7 = 4
Total odd days = (4 + 6 + 4) = 14 ÷ 7 = 0(remainder)
The number of odd days from 19 July 2012 to 11 January 2018 = 0
So, zero odd days will be added to thursday.
Thus, the day of the week on 11 January 2018 = Thursday
