The two necessary conditions for the same calendar is;

1) Both years must either be normal or both leap.
2) A number of odd days between two years must be 0.

If the year is leap then add 28 to get the same calendar provided that no century year which does not leap should fall in between.

If the year is not leap, add 11 and if the result is not leap; the result has the same calender. If the result is leap then add 6 to get same calender. It should be taken that no century year which is not leap should not fall in between.

2007 is not leap so 2007+11=2018, 2018 is not leap; hence 2018 is the answer.

2007 is a general year so either it will repeat after year or 11 year let's see;

Year : 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017.
Odd day : 1 1 2 1 1 1 2 1 1 1 2 .

If the addition is 7 then the calendar will change but 2012 is leap year so general year can't be a leap year so now we go till the 14.

In these types of questions, divide last 2digits of the given year from 4, after that if divisible is--
2 and 3 add 11in it,
1 add 6 in it,
0 add 28 in it.

Eg.2007(07/4) divisible is 3 so add 11 in 2007= 2018.

@All.

A leap year calendar repeats itself in 28 years and an Ordinary year Calender repeats itself in 6 or 11 years.

Here, we can simply add 2007+6=2013 (which is not there in the option) and 2007+11= 2018 which is the answer.
