Answer 1

Answer: (A)

Saturday

Given, it was Saturday on 18 December 1982.
We know that 1982 is an ordinary year which has only 1 odd day.
Therefore, 18 December 1983 is Sunday.
So, 25th Dec 1983 and 1 Jan 1984 is also a Sunday and 1984 is a leap year.
Now, In 1984, till 22nd Sep, the number of odd days is calculated as follows:
Month Jan Feb Mar Apr May Jun July Aug Sept
Days 30(= 31 - 1) + 29 + 31 + 30 + 31 + 30 + 31 + 31 + 22 = 265 days or 37 weeks and 6 odd days.
Therefore, the day on 22nd September 1984 is 6 days after Sunday(on 1 Jan 1984) i.e., Saturday.
Hence, the day on 22nd Sep 1984 is Saturday.
