26th January of a certain year is a Sunday. On which day of the week did 25th December of the year before fall?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Wednesday
Count the days from the earlier date to the later one and keep only the odd days (days left over after whole weeks). Going back in time, the weekday moves back by that many days.
25th December to 31st December: \(31-25=6\) days
31st December to 26th January: 26 days
Total \(=6+26=32\) days \(=4\times7+4\), so 4 odd days
4 days back from Sunday: Saturday, Friday, Thursday, Wednesday
