If 29th March, 1995 was a Wednesday, then what day of the week was 1 November, 1994?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Tuesday
Count the days from 1 November 1994 to 29 March 1995 and keep only the odd days (the remainder after dividing by 7); the weekday moves forward by that many days. February 1995 has 28 days, since 1995 is not a leap year.
November 1994 (from 1 Nov to 30 Nov, the 1st not counted): 29 days
December 1994: 31 days
January 1995: 31 days
February 1995: 28 days
March 1995 (up to the 29th): 29 days
Total: \(29+31+31+28+29=148\) days
\(148=21\times7+1\), so 1 odd day
29 March 1995 is 1 day ahead of 1 November 1994 in the week. Going one day back from Wednesday gives Tuesday.
