If 6th March, 2005 is Monday, what was the day of the week on 6th March, 2004?
Sunday
Saturday
Tuesday
Wednesday
Explanation:

The year 2004 is a leap year. So, it has 2 odd days.

But, Feb 2004 not included because we are calculating from March 2004 to March 2005. So it has 1 odd day only.

The day on 6th March, 2005 will be 1 day beyond the day on 6th March, 2004.

Given that, 6th March, 2005 is Monday.

6th March, 2004 is Sunday (1 day before to 6th March, 2005).

I can't understood jegadish can you explian how you put 3 odd days and 6 odd days like that.

If you want check calender. your logic was correct for normal years but 2004 is leap year so (-2) need to be done. other best way of solving is

2004 = 2000+3years+march 6
= (0 odd days)+(3 odd days)+(jan(3odd days)+feb(1odd day as it is leapyear)+(march 6=60dddays))
=3+3+1+6
=13(7+6)
=6 odd days(6 means sat)

In this 6 mar 2004 - 6 mar 2005 the answer is (-1). So the answer is one day before i.e. Monday before is 'Sunday'.

6th March, 2004 is Sunday.

So,1 day before to 6th March is 2005.

The given data is 'If 6th March, 2005 is Monday' - here we have to consider it as Monday (but actually 6th March, 2005 is Sunday).

As per the calculation 6th March, 2004 is one before to 6th March 2005.

Therefore, one day before to 'Monday' is 'Sunday'.

Note: Please do not check the with the original calendar to find the day of 6th March, 2004. Because the given data is an assumption.
