3. An instructor has a class with 150 students enrolled in it. In a class meeting she noticed that many but not everyone showed up. When she asked the students to self-countby every 3 (i.e, call out 1,2,3,1,2,3…) she observed that there were 2 students left (i.e., the total number of students in 3N+2, N is unknown). She repeated the count for every 5 students, she found 3 were left. Counting every seven students just left 1. What is the total of students in the classroom? Solve this problem without using algebraic equations.
