Detailed Solution
Download Solution PDFGiven: 16 September 2010 was Thursday.
Now,
2010 to 2017 = 7 Years (5 Ordinary Years and 2 Leap Years).
So, 2 Leap Years have 4 odd days,
And, 5 Ordinary Years have 5 odd days.
Total odd days = 4 + 5 = 9.
9 odd days → 9/7 = 1 week and 2 odd days.
then, 16 September 2017 will be Thursday + 2 = Saturday.
Now, the number of days between 17 August 2017 to 16 September 2017
= 14 (August) + 16 (September) = 30 days.
= 30 days → 30/7 = 4 weeks and 2 odd days.
So, 17 August 2017 will be Saturday - 2 = Thursday.
Hence, the correct answer is "Option 2".
