Answer

To determine what day of the week it was on 6th November 1987, given that 4th April 1988 was a Monday, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Date Difference**:
We need to find the number of days between 6th November 1987 and 4th April 1988.

2. **Calculate Days in November 1987**:
From 6th November to 30th November, there are:
- 30 - 6 = 24 days remaining in November.

3. **Calculate Days in December 1987**:
December has 31 days.

4. **Calculate Days in January 1988**:
January also has 31 days.

5. **Calculate Days in February 1988**:
Since 1988 is a leap year, February has 29 days.

6. **Calculate Days in March 1988**:
March has 31 days.

7. **Calculate Days in April 1988**:
From 1st April to 4th April, there are 4 days.

8. **Total Days Calculation**:
Now, we add all these days together:
- Days in November: 24
- Days in December: 31
- Days in January: 31
- Days in February: 29
- Days in March: 31
- Days in April: 4

Total = 24 + 31 + 31 + 29 + 31 + 4 = 150 days.

9. **Calculate Weeks and Odd Days**:
Now, we need to find out how many complete weeks are in 150 days:
- 150 days ÷ 7 days/week = 21 weeks and 3 days.
This means there are 3 odd days.

10. **Determine the Day of the Week**:
Since 4th April 1988 is a Monday, we need to go back 3 days:
- 1 day back from Monday is Sunday.
- 2 days back is Saturday.
- 3 days back is Friday.

Thus, 6th November 1987 was a **Friday**.

### Final Answer:
**Friday**
