Answer 2

Answer with explanation:

Number of days in a year , considering the year is non leap year =365 days

It means there are 52 weeks in a year ,that is there are 52 sundays.And one day is left ,so it can be either of seven days.So, there can be either 52 sundays or 53 sundays in a year.

For a leap year

 366= 52 × 7 + 2

It means there are 52 weeks in a year ,that is there are 52 sundays.And two days are left .So, there can be either 52 sundays or 53 sundays in a leap year also.
