Correct Answer - Option 4 :
Tuesday
When finding the reference date without reference date then formula will be:(Century code+ Year code + Month code + Date code)/7
Day Codes:
Sunday = 0
Monday = 1
Tuesday = 2
Wednesday = 3
Thrusday = 4
Friday = 5
Saturday = 6
Month Codes:
Jan = 1
Feb = 4
Mar = 4
Apr = 0
May = 2
Jun = 5
Jul = 0
Aug = 3
Sep = 6
Oct = 1
Nov = 4
Dec = 6
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 1865 is 2.
The year code can be find through (last 2 digit of year + (last 2 digit of year/4))/7.
(65 + 65/4)/7 = (65 + 1)/7 = 3
Here remainder will be 3 so year code will be 3
The code for April for non leap year: 0
The code for date will be date/7, here remainder will be 4 so code for date will be 4
Summing up,
(2 + 0 + 3 + 4) / 7 = 9/7
Here remainder is 2 which is code for Tuesday in below given list to on April 18, 1865 day will be Tuesday.
