Hey there !

Solution:

This question requires knowledge of odd days and calendar.

Let us solve this step by step.

Now let us know what the term odd days mean.

Odd days is the remainder obtained, when the total number of days in a month is divided by 7.

E.g. If a month has 31 days, then when divided by 7 we get remainder as 3. So Odd days for that month is 3.

Now let us solve your question.

Let us count the number of days between March 18, 1994 and February 25, 1995.

March = 31 - 18 = 13 days. Therefore Odd days =  6 days

April = 30 days => Odd days = 2 days

May = 31 days => Odd days = 3 days

June = 30 days => Odd days = 2 days

July = 31 days => Odd days = 3 days

August = 31 days => Odd days = 3 days

September = 30 days => Odd days = 2 days

October = 31 days => Odd days = 3 days

November = 30 days => Odd days = 2 days

December = 31 days => Odd days = 3 days

January = 31 days => Odd days = 3 days

February = 25 days => Odd days = 4 days

Sum of all Odd days / 7 is the Net Odd day number.

Sum of all odd days = 36 / 7 which has a remainder 1

So Net Odd day number is 1.

So February 25th would have a day which is 1 day after friday.

Therefore Saturday is the day after Friday.

Hence the answer is Saturday.

The answer given in the key is wrong.

Hope my answer helped !
