Answer:
D. Monday
Read Explanation:
Solution:
When finding the day without reference date then formula will be: (Century code + Year code + Month code + Date code)/7
Day Codes:
Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
0 | 1 | 2 | 3 | 4 | 5 | 6 |
Month Codes:
Jan = 0
Feb = 3
Mar = 3
Apr = 6
May = 1
Jun = 4
Jul = 6
Aug = 2
Sep = 5
Oct = 0
Nov = 3
Dec = 5
Century Codes:
1500 - 1599 = 0
1600 - 1699 = 6
1700 - 1799 = 4
1800 - 1899 = 2
1900 - 1999 = 0
2000 - 2099 = 6
2100 - 2199 = 4
2200 - 2299 = 2
2300 - 2399 = 0
Century code for 1800 is 2.
The year code can be found through (last 2 digit of year + (last 2 digit of year/4))/7.
(65 + (65/4))/7
Here remainder will be 4 so year code will be 4
The code for December is: 5
The code for the date will be date/7,
25/7
here remainder will be 4 so code for the date will be 4
Summing up,
(2 + 4 + 4 + 5)/7
Here remainder is 1 which is code for Monday.
So on 25th December, 1865 day will be Monday.
Hence, the day is Monday.
