Answer 2

Answer:

The day of the week will be 31st December 2013 is Tuesday.

Step-by-step explanation:

It is given that 1st January 2013 was Tuesday.

The number of days in a week is 7.

Total number of days in a year is 365.

Number of days between 1st January 2013 and 31st December 2013 is 364.

$\frac{364}{7}=52$

Since the number of days between 1st January 2013 and 31st December 2013 is completely divisible by 7, therefore the day on 1st January 2013 and 31st December 2013 are same.

Thus the day of the week on 31st December 2013 will be Tuesday.
