Correct Answer
Explanation
Output: 15th August, 1947 = ( 1946 years + January 1st, 1947 to 15th august, 1947)
Counting odd days:
1600 years = 0 odd day. 300 years = 1 odd day.
46 years = (11 leap years + 35 ordinary years)
[(11×2) + (35×1)] odd days = 57 odd days => 8 weeks + 1 days = 1 odd days.
1946 = (0 + 1 + 1) odd days => 2 odd days.
Jan(31) + Feb(28) + March(31) + April (30) + May(31) + June(30) + July(31) + August(15) = 227 days = (32 weeks + 3 day) => 3 odd day.
Total number of odd days: 2+3 => 5 odd days.
The answer is Friday.
