Answer:

D) Sunday

Explanation:

 It was Saturday on 31st December, 2005.

 Number of odd days from 2006 to 2009 = (1 + 1 + 2 + 1) = 5 days.

Hence on December 31, 2009, it was Thursday. Thus, on Jan 3, 2010 it was Sunday. 

Answer:

D) Rs. Tuesday

Explanation:

 We know year 2004 is a leap year. Therefore, it has 2 odd days.

 Feb 2004 was not included as we are calculating from March 2004 to March 2005.

So it has 1 odd day. 

The day on March 13, 2005 will be 1 day ahead of the day on March 13, 2004.

Given that, March 13, 2005 is Wednesday.

So March 13, 2004 is Tuesday (1 day before to 13th March, 2005).

Answer:

C) Saturday

Explanation:

100 years contain 5 odd days.

Therefore, Last day of 1st century is Friday

200 years contain (5 x2) is 3 odd days (approx.)

Last day of 2nd century is Wednesday

300 years contain ( 5x3) = 15 i.e. 1 odd day( approx.)

Last day of 3rd century is Monday 400 years contain 0 odd day

Last day of 4th century is Sunday.

Thus, the cycle is repeated.

Last day of a century cannot be Tuesday or Thursday or Saturday.

∴On December 31, 2009, it was Thursday, so on January 1, 2010, it was Friday.

Answer:

B) Friday

Explanation:

Total number of odd days between the years 2002 and 2006 = (2006 - 2002) + 1 = 5 odd days. The year 2004 is a leap year, it has two odd days. So, one extra odd day is added.
