In a mathematics competition, students are required to form teams. Every team consists of 6 or 7 students from the same school. n students has been selected by school A and n from school B for the competition.

On the plane there are three circles with radii 1, 2, 3 respectively and the distance between the centers of any two of them is 10. If a fourth circle C is to be added on the plane such that C meets each of the three original circles at exactly one point, how many different circles C are possible ?
Dates are written as 'YY/MM/DD', a six-digit number. For example, 7th March 2004 is represented as 04/03/07. Now as 04 + 03 = 07 , we call it a 'good day'. In general, a day is said to be a 'good day' if, among the three two-digit numbers used for 'year', 'month' and 'day' in the above representation, one of them is equal to the sum of the other two. How many 'good days' are there in the 21st century (from 1st January 2001 to 31st December 2100)?
