Here is another one, JEN gave birth to her daughter ...

This answer was rated:

Here is another one, JEN gave birth to her daughter Caroline on the first of January in a year following leap year. Starting in February, on the first of the month throughout that year, she made note of the day of the week. She noticed that the monthly anniversary of her daughter's birth fell on a Friday 3 times that year. On what day of the week was Caroline born? And how many months old was Caroline before her monthly "birthday" fell on its origanal day for the third time (not counting her actual day of birth)?


Caroline was born on a Tuesday.

She was 9 months old the first time, 15 months the second time, and 18 months the third time,

So, the answers are Tuesday, and 18 months.

Hope this is the answer you're looking for!
