Correct Answer - Option 1 : Monday
15th August, 200 = (2049 years + Period from 1st January 2050 to 15th August 2050)
Odd days in 1600 years = 0
Odd days in 400 years = 0
49 years = (12 leap years + 37 ordinary years) = (12 x 2 + 37 x 1) = 61 odd days = 5 odd days
Odd days in the year 2050 =
January = 3, February = 0, March = 3, April = 2, May = 3, June = 2, July = 3 , August = 1
Total odd days in 2050 till 15th August = 3 + 0 + 3 + 2 + 3 + 2 + 3 + 1 = 17 odd days or 3 odd days
Total odd days = 5 + 3 = 8 odd days or 1 odd day.
Days on odd days:
0 odd days = Sunday
1 odd days = Monday
2 odd days = Tuesday
3 odd days = Wednesday
4 odd days = Thursday
5 odd days = Friday
6 odd days = Saturday
Therefore, It will be Monday on 15th August 2050.
Hence, Monday is correct.
