If in a particular year 12th January is a Sunday, then which one of the following is correct?
15th July is a Sunday if the year is a leap year.
15th July is a Sunday if the year is not a leap year.
12th July is a Sunday if the year is a leap year.
12th July is not a Sunday if the year is a leap year.
Solution
From 12th January to 12th July in a leap year, the number of days elapsed is exactly a multiple of 7 (182 days = 26 weeks, counting Jan remaining + Feb 29 + Mar + Apr + May + Jun + 12 of Jul). Since the gap is a whole number of weeks, 12th July falls on the same weekday as 12th January, i.e. Sunday. Hence option C is correct.
