If March 24, 2011 was Thursday, what was the day on June 24, 2012?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Sunday
The weekday moves on by the number of odd days, the days left over after whole weeks. An ordinary year has 1 odd day and a leap year 2; a month of 30 days has 2, and one of 31 days has 3.
March 24, 2011 to March 24, 2012 (one full year):
It includes 29 February 2012, so it has 366 days: 2 odd days
March 24, 2012 to June 24, 2012, month by month:
March 25 to 31: 7 days, 0 odd days
April: 30 days, 2 odd days
May: 31 days, 3 odd days
June 1 to 24: 24 days, 3 odd days
Adding up:
Total odd days: \(2+0+2+3+3=10\), that is 1 week and 3 days
Thursday + 3 days = Sunday
