If 21st June 2007 was Thursday, then what day of the week was it on 21st June 2011?

Solution

✅ Correct Option: 3

From 21 June 2007 to 21 June 2011 is 4 years. The day of the week advances by 1 for each ordinary year and 2 for each year whose intervening Feb 29 falls in the span. Feb 2008 (leap) falls within June2007-June2008, giving +2; the other three year-spans each give +1.

Total advance =2+1+1+1=5= 2+1+1+1 = 5 days. Thursday + 5 days = Tuesday.
