Answer

To determine the day of the week on 5th November 1987, given that 4th April 1988 was a Monday, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given information**:
- We know that 4th April 1988 is a Monday.

2. **Count the months between the two dates**:
- The months between 5th November 1987 and 4th April 1988 are:
- November 1987 (from 5th to 30th)
- December 1987
- January 1988
- February 1988 (Leap Year)
- March 1988
- April 1988 (up to the 4th)

3. **Calculate the number of days in each month**:
- **November 1987**: 30 days (from 5th to 30th = 30 - 5 + 1 = 26 days)
- **December 1987**: 31 days
- **January 1988**: 31 days
- **February 1988**: 29 days (Leap Year)
- **March 1988**: 31 days
- **April 1988**: 4 days (up to the 4th)

4. **Total the days**:
- Total days = 26 (Nov) + 31 (Dec) + 31 (Jan) + 29 (Feb) + 31 (Mar) + 4 (Apr)
- Total days = 26 + 31 + 31 + 29 + 31 + 4 = 152 days

5. **Calculate the number of weeks and remaining days**:
- Divide the total days by 7 to find the number of weeks and extra days:
- 152 ÷ 7 = 21 weeks and 5 days (since 21 * 7 = 147, and 152 - 147 = 5)

6. **Determine the day of the week**:
- Since 4th April 1988 is a Monday, we subtract the 5 extra days to find the day on 5th November 1987:
- Monday - 5 days =
- Sunday (1 day back)
- Saturday (2 days back)
- Friday (3 days back)
- Thursday (4 days back)
- Wednesday (5 days back)

Thus, the day on 5th November 1987 was **Wednesday**.
