A school currently maintains a fixed number of students per class. If the ratio of students per class were to be increased by 1, 10 fewer classes would be run for a total of 120 students. What is the current ratio of students per class?	Options
A) 3 B) 4 C) 6 D) 8 E) 12
Number of classes now : 120/x, where x is the number of students per class.   When it is increased by 1, Number of classes will be 120/(x+1).   We are told, 120/x - 120/(x+1) = 10 =&gt; Solving x = 3.   3NSWER:3
