1. Arun went for a movie nine days ago. He goes to watch movies only on Thursdays. What day of the week is today?
a) Friday
b) Thursday
c) Wednesday
d) Saturday

Explanation:
Clearly it can be understood from the question that 9 days ago was a Thursday
Number of odd days in 9 days = 2 (As 9 - 7 = 2, reduced perfect multiple of 7 from total days)
Hence today = (Thursday + 2 odd days) = Saturday

2. January 1, 2007 was Monday. What day of the week lies on Jan. 1, 2008?
a) Sunday
b) Tuesday
c) Monday
d) Wednesday

Explanation:
The year 2007 is an ordinary year. So, it has 1 odd day.
1st day of the year 2007 was Monday.
1st day of the year 2008 will be 1 day beyond Monday.
Hence, it will be Tuesday.

3. What was the day of the week on 24th July 2011?
a) Sunday
b) Wednesday
c) Monday
d) Tuesday

Explanation:
Formula : (Date + Month code + No.of years + No.of leap year + Century code)/7
\eqalign{ & = \frac{{24 + 0 + 11 + 2 + 6}}{7} \cr & = \frac{{43}}{7} \cr & = 1 \cr & = {\text{Sunday}} \cr}

4. How many days will there be from 26th January, 1996 to 15th May, 1996 (both days included)?
a) 113
b) 111
c) 110
d) 112

Explanation:
Number of days from 26-Jan-1996 to 15-May-1996 (both days included)
= 6(Jan) + 29(Feb) + 31 (Mar) + 30(Apr)+ 15(May)
= 111

5. On 8th Feb, 2005 it was Tuesday. What was the day of the week on 8th Feb, 2004?

a) Thursday
b) Wednesday
c) Tuesday
