Question

If 9th December, 2007 is Sunday, then what was 8th July, 2007?

• A. Tuesday
• B. Thursday
• C. Friday
• D. Saturday

Hint:

If the day gap is a multiple of 7, the weekday is unchanged.

Answer 1

The Correct Option is B

Days between 8 Jul 2007 and 9 Dec 2007 \(=\) 154 \(=\) \(22\) weeks \(\Rightarrow\) same weekday.
Since 9 Dec 2007 is Sunday, 8 Jul 2007 is also Sunday.
\(\Rightarrow\) None of the given options match; the official key’s “Thursday” conflicts with the calendar.
