Answer 1

The correct option is B Tuesday

Number of days from $\text{3 November 1987 to 4 April 1988}$ is $153$, as calculated below:
1987 November have 27(= 30-3) days,
1987 December have 31 days,
1988 January have 31 days,
1988 February have 29 days (being a Leap year),
1988 March have 31 days,
1988 April have 4 days upto 4th april
So, total number of days from 3rd Nov; 1987 to 4th Apr; 1988 = 27 + 31 + 31 + 29 + 31 + 4 = 153 days
$153$ days, means $\text{21 weeks + 6 days}$. So, there are $6$ odd days.
Thus, $\text{3 November 1987}$ was $6$ days earlier to Monday. So, the day was Tuesday on 3 November 1987.
