It was Sunday on Jan 1, 2006. What was the day of the week Jan 1, 2010?
Answer: Option
Explanation:
On 31st December, 2005 it was Saturday.
Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.
On 31st December 2009, it was Thursday.
Thus, on 1st Jan, 2010 it is Friday.

Simple in question we have 2006 Jan 1 to 2010 Jan 1.
Here 2006, 2007, 2008, 2009, 2010.
In this number of odd days in each year is 1 but 2008 is is the leap year. So we can take extra one day so it is 2.
Then now total number of odd days is 6.
Now from Jan 1 2006 Sunday to 6th day of Jan 1 2010 is Friday.
I think it is helpful.

Days:
S=1.
M=2.
T=3.
W=4.
Th=5.

Sat=7 or 0.
Formula = Day+month no. + (x-1900) + (x-1900) /4.
X = The year we have to calculate.
