If 11 October 1965 is Monday, then what will be the day of the week on 15 July 1973?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Sunday.
No. of days from 11 October 1965 to 31 December 1965 = 20 + 30 + 31 = 81
No. of days from 1 January 1966 to 31 December 1972 = (7 × 365) + 2 = 2557 (2 leap years)
No. of days from 1 January 1973 to 15 July 1973 = 31 + 28 + 31 + 30 + 31 + 30 + 15 = 196
So, the total no. of days from 11 October 1965 to 15 July 1973 = 81 + 2557 + 196 = 2834 ÷ 7 = 6 (Remainder)
Thus, Monday + 6 = Sunday
