Answer 2

Answer:

Saturday

Step-by-step explanation:

'December 31, 2012'...

This is Monday. And we have to find the day of December 31, 2011.

Please remember that the year 2012 is a leap year!!!

Such that 2 days should be deducted from the day of December 31, 2012 to get the day of December 31, 2011.

   

Why we have to do this?!

Because an ordinary year has 52 weeks and 1 odd day, and a leap year has 52 weeks and 2 odd days.

So that the difference between the days of December 31, 2011 and December 31, 2012 is 366, which equals the no. of days in a leap year. So that the no. of odd days is 2, thus the day of December 31, 2012 is 2 days after that of December 31, 2011.

Which means that, to find the day of December 31, 2011 if the day of December 31, 2012 is given, then deduct the no. of odd days in 2012, i.e., 2, from the day of December 31, 2012.

 

Thus the answer is Saturday.
