What was the day of the week on 16th August, 1947?
a) Sunday
b) Monday
c) Saturday
d) Thursday
Answer: c
Explanation: 15th August, 1947 = (1946 years + Period from 1st Jan., 1947 to 15th )
Counting of odd days:
1600 years have 0 odd day. 300 years have 1 odd day.
47 years = (11 leap years + 36 ordinary years)
= [(11 x 2) + (36 x 1) ] odd days
= 58 odd days
= 2 odd days
Jan Feb Mar Apr May Jun Jul Aug
= 31 + 28 + 31 + 30 + 31 + 30 + 31 + 15
= 227 days
= (32 weeks + 3 days)
= 3
Total number of odd days
= (0 + 1 + 2 + 3) odd days
= 6 odd days
Hence, the required day was ‘Saturday’.
