If 31 December 2009 was Thursday, then what was the day of the week on 25 December 2010?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3. i.e. Saturday.
If 31 December 2009 was Thursday then,
Number of odd days in 2010(not a leap year) = 1
Thus, Thursday + 1 = Friday
31 December 2010 will be Friday.
Now, 25 December 2010 = Friday - 6 = Saturday.
So, 25 December 2010 was Saturday.
Hence, the correct answer is 'Option 3'.
