26 january 1950 which day of the week?

A) Monday
B) Wednesday
C) ThursdayD) Tuesday

Before solving this we should be aware of Odd days concept. Odd days are the days more than complete weeks
Odd days:
0: Sunday; 1: Monday; 2: Tuesday ; 3: Wednesday; 4: Thursday ;
5: Friday; 6: Saturday
The number of odd days in 400/800/1200/1600/2000 years are 0.
Hence, the number of odd days in the first 1600 years is 0.
Number of odd days in 300 years = 1
Number of odd days in 49 years = (12 x 2 + 37 x 1) = 61 days = 5 odd days
Total number of odd days in 1949 years = 1 + 5 = 6 odd days
Now look at the year 1950
January 26 = 26 days = 3 weeks + 5 days = 5 odd days
Total number of odd days = 6 + 5 = 11 => 4 odd days
Hence, Thursday.
