Twice as many students attend math class compared to people who attend history class. If 2 people began attending history class instead of math class, the ratio of math students to history students would be 1 to 1. How many students total attend these two classes? Hint: No students attend both math and history class.	Choose the correct answer
A) 12
B) 16
C) 90
D) 36
E) None of the Above
By checking the answer choices:   Since we have an initial ratio of 2:1, the total count should be divisible by 3.   A. 12/3=4, Math Students = 8, History Students = 4, Since 8-2 is equal to 4+2 this is the correct answer.   B. Out, Since not divisible by 3.   C. 90/3=30, Math Students = 60, History Students = 30, Since 60-2 is not equal to 30+2, this is not the answer.   D. 36/3=12, Math Students = 24, History Students = 12, Since 24-2 is not equal to 12+2 this as well can not be the answer.   E. Since choice A is correct, choice E is not correct.   12 is the correct answer.
