Step-by-step explanation:

Answer 2

Answer: Friday

Step-by-step explanation:

In a certain leap year , we know on 13th january it was Saturday .

No. of days between 13th January and 15th March on the same year (including 15th March , excluding 13th January) = (31 - 13) + 29 + 15     (There are 29 days on February as it is a leap year)

=> 18 + 29 + 15

=> 62 .

Divide 62 by 7 , to get the number of weeks .

On dividing 62 by 7 , we get Quotient 8 and remainder 6 .

That means 62 days = 8 weeks + 6 days .

Here the no. of odd days is 6

Note that if it was Saturday today , will definitely will be a Saturday next week So after 8 weeks , it will be a Saturday .

After 6 days , it will be a Saturday - Sunday - Monday - Tuesday - Wednesday - Thursday - Friday .

Hence on 15th March on the same year  , the day will be a Friday .
