Classes A, B, and C have a total of 144 students. First, the same number of students as Class B is transferred from Class A to Class B, and then the same number of students as Class C is transferred from Class B to Class C. Call out the same number of people as Class A at this time to Class A, so that the number of classes A, B, and C will be equal. How many people are there in Class A?
