If 22 April 2013 was a Monday, then what was the day of the week on 22 April 2012?

ASunday ✓ Correct

BSaturday

CTuesday

DWednesday

Correct answer: (A) Sunday

Explanation

22 April 2012 was a Sunday.

From 22 April 2012 to 22 April 2013 the February in between (2013) is ordinary, so the gap is 365 days.

365 days give a remainder of 1 on division by 7, i.e. 1 odd day.

So 2013 is one weekday ahead of 2012; going back subtracts 1.

Monday - 1 = Sunday.
