Suppose today is Friday, what day of the week will it be 65 days from now?

Answer: Option B

The day of the week repeats every 7 days.
Given today is Friday. Again Friday is repeated on the 7^th day, 14^th,... on 7 multiple days.
Hence, Friday is on the 63^rd day, as 63 is multiple of 7.
Now, the required day of the week on the 65^th day is Sunday.
