Sam's birthday is 186 days after Jim's birthday. Susan's is 24 days after Jim's. Sam was born on September 6th. What day was Susan born on if it wasn't a leap year?

Well, there are 365 days in a year, as you well know. I would either go on a search engine and google, what number day of the year is September 6th, or by counting on a calendar, find how many days there are between September 6th and December 31st, and subtract that from 365 to find what number day of the year September 6th is. Then, just add 24!
Hope I helped! :) 
looks like an exercise in counting forwards and backwards, knowing how many days there are in each month.

December 27

The anwser is she was born on the 273 day which is October 1.
