I = Prt
I= interest in dollars
P = the amount of money
r = the rate
t = time
200 = (400)*(0.12)(t)
t = 200/(400*0.12)
This is just a guess, it's been a long time since I've had to do these problems :-/

ok i'll assume you are only paying the interest each month
400*r*t = 200
monthly rate is 1%
4 t = 200
t = 50 months
