If 15 August 2006 is a Tuesday, then what will the day of the week on 19 February 2012?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Sunday.
Number of leap years = 1; Number of normal years = 4
Total odd days from 15 August 2006 to 15 August 2011 = (2 × 1) + (1 × 4) = 6 odd day
Number of odd days from 15 August 2011 to 19 February 2012:
16 (Aug) + 30 (Sep) + 31 (Oct) + 30 (Nov) + 31(Dec) + 31 (Jan) + 19 (Feb) = 188/7 = 6 odd days
Total odd days = 6 + 6 = 12/7 = 5 odd day
⇒ Tuesday + 5 odd days = Sunday
Thus, if 15 August 2006 is a Tuesday, then on 19 February 2012 it will be Sunday.
