Useful conversions:
25% = 1/4
37.5% = 3/8
25 percent of n equals 37(1/2) percent of m
In other words, 1/4 of n equals 3/8 of m
We get: n/4 = 3m/8
What is the value of 12n/m?
Take n/4 = 3m/8
Cross-multiply to get: (8)(n) = (3m)(4)
Simplify: 8n = 12m
Divide both sides by m to get: 8n/m = 12 [ALMOST THERE!!!]
Multiply both sides by 1.5 to get: 12n/m = 18
Answer: A

or; 1/4*n= 75/2* 1/100*m
n=3/2*m
Substitute n in 12n/m
=(12*1.5m)/m
=18
Answer A
n=3/2*m
Substitute n in 12n/m
=(12*1.5m)/m
=18
Answer A
