View Answer

A) Friday

Explanation : Calculating the number of odd days in 1947 = 1600 + 300 + 46 years + 1st jan 1947 to 15th Aug 1947
1600 years has 0 odd days
300 years has 1 odd day
46 years has 11 leap years and 35 normal years which is 11 × 2 + 35 × 1 = 57 odd days or simply 1 odd days.
In the 1947, number of days up to 15 august,
31 + 28 + 31 + 30 + 31 + 30 + 31 + 15 = 227 or 3 odd days.
Total odd days is 1 + 1 + 3 = 5 odd days.
So the required day was Friday.
Hence Friday is the correct answer.
