If 15th of February, 1789 is Friday, what will be the day of 15th of February 1790 ?

Correct option is C

Solution: Day of the Week Calculation

Problem: If 15th February 1789 is a Friday, what will be the day of the week on 15th February 1790?

Solution

Step 1: Check if 1790 is a Leap Year

A year is a leap year if:
1. It is divisible by 4.
2. It is not divisible by 100 unless also divisible by 400.

Since 1790 is not divisible by 4, it is **not a leap year**.
Thus, 1789 has 365 days, which is exactly 52 weeks and 1 extra day.

Step 2: Calculate the Day

From 15th February 1789 (Friday):
- Add 1 extra day for the non-leap year 1789.

Therefore, 15th February 1790 will be **Saturday**.

Final Answer:

The day on 15th February 1790 is **Saturday**.
