If 18 October 2006 was Wednesday, then what was the day of the week on 17 October 2000?

Solution

✅ Correct Option: 4

If 18 October 2006 was a Wednesday, then 17 October 2006 was a Tuesday.

From 17 October 2000 to 17 October 2006 spans six years containing exactly one 29 February, that of 2004, so the gap is 6×365+1=21916 \times 365 + 1 = 2191 days.

Since 2191=313×72191 = 313 \times 7, there are zero odd days, so 17 October 2000 was also a Tuesday.
