Easy Grades 10 and 9 went on a field trip. There were 12 more 9s than 10s and there were 120 children in all. How many year 9s were there?

Hard There is a nine digit number 2B0RN0T2B. Digits others than 2 and 0 are represented as letters. Each letter represents one number, and no letter can be the 2 or 0. The number is a multiple of both 5 and 9. What is the highest possible value of 2B0RN0T2B?
