Solution
The correct option is E Friday Given, 25 December 1987, was Friday. So, 1 Jan 1988 is also a Friday. Now, between the date 1 Jan 1984 and 31st Dec 1987 we have 1 leap year and 3 non-leap year. Number of odd days = 1 X 2 + 3 X 1 = 5 odd days Therefore, if 1 Jan 1988 is a Friday then 1 Jan 1984 is 5 days before Friday i.e, Sunday. So, 6 Jan 1984 is clearly a Friday. Hence, they both met first on Friday, 6 Jan 1984.
