Correct option is B)
15th August 1947 has 1946 years and period from 1st January 1947 to 15th August 1947.
Now, first 1600 years have 0 days.
Next 300 years have 1 odd day.
46 years = 11 leap years + 35 non leap years = 11×2+35=57days = 1 odd day
Number of days from 1st Jan 1947 to 15th August 1947 = 227 days = 3 odd days
Hence, total number of odd days = 0+1+1+3=5
Hence, if 0 odd day it is Sunday, 1 odd day it is a Monday and so on.
Hence 5 odd days is a Friday.
