Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Tuesday.
No. of odd days from 21st June 2007 to 21st June 2008 = 2
No. of odd days from 21st June 2008 to 21st June 2009 = 1
No. of odd days from 21st June 2009 to 21st June 2010 = 1
No. of odd days from 21st June 2010 to 21st June 2011 = 1
Total number of odd days = 2 + 1 + 1 + 1 = 5
The day of the week on 21st June 2011 = The day of the week on 21st June 2007 + 5 days
= Thursday + 5 days = Tuesday
