2004 is a leap year (Since the month of February in this year has 29 days).
Now, March 11, 2003 is a Tuesday. We have to find the day of the week on March 11, 2004.
The number of days between the two dates is 366 days.
The number of odd days is 2.
The day of the week on March 11, 2004 = Tuesday + 2 = Thursday

Apply direct formula for gain or loss, we get where hands coincide after x minutes= 80.23
Since this value is positive, so there will be a gain.

Since today is Wednesday, therefore after 91^st day, it will be Wednesday, as 91 is a multiple of 7.
Hence, the day after 94 days will be a Saturday.

Months: Mar, Apr,  May,  June,  July,  Aug,  Sept, Oct
Odd days: 3,  2, 3,  2, 3, 3, 2, 3 
Total 21 odd days 
21/7 = 0
So, November will start with the same day.

Total holidays are 6 and the number of days in January is 31. Number of working days = 31 - 6 = 25. Thus, this option is correct.

In 30 years from 1971 to 2001, number of odd days = 30 + 8 (from leap years) = 38 odd days
It gives 3 odd days after being divided by 7.
So, December 9, 1971 is Thursday (three days before Sunday).

Given: 13th October, 2002 was Sunday.
So, 13th October, 2003 was Monday.
12th October, 2003 was Sunday.
So, 19th October, 26th October and 2nd November were Sundays.
Hence, the first Sunday in November 2003 fell on 2nd.

1990 was not a leap year and had only 1 odd day.
Therefore, January 1, 1991 will be Tuesday.

There are 365 days between 2nd July, 1984 and 2nd July, 1985.
In 365 days, there are 52 weeks and 1 odd day.
If 2nd July, 1985 was a Wednesday, then
2nd July, 1984 was the day that comes before Wednesday which means Tuesday.

Local time varies only with longitudes.
The flight travelled from 10E to 70W longitudes i.e. 80° longitudes.
Time change because of longitude change = 80 × 4 = 320 minutes = 5 hours and 20 minutes
Time at 18N 10E after 10 hour journey = 2 am + 10 hours = 12 pm
Because the flight travelled towards West from East, the local time at 36N 70W
= 12 pm - 5 hrs 20 m = 6:40 am
