If mn ≠ 0 and 25 percent of n equals 37 1/2 percent of m, what is the value of 12n/m?  Choose the correct choice from the following options:	A) 18	B) 323323	C) 8	D) 3	E) 98

Rationale: given : 25 percent of n equals 37 ( 1 / 2 ) percent of m = > ( 25 / 100 ) * n = ( 75 / 200 ) * m = > 2 n = 3 m . 12 n / m = 6 * 2 n / m = 6 * 3 m / m = 18 . hence a .
Answer: A
