-------------------
I = prt
50 = 200*0.02*t

50 = 4t
t = 12.5 years

Simple interest is nothing more than the interest rate times the original principal each interest paying period. You don't say, so I presume annual. 200 times 2% is 4.00. 4 goes into 50 12.5 times. The thing is, unless they are paying the interest at 6 month intervals (or more frequently) you will never have exactly $50 interest. At the end of the 12th year you will have 48 bucks, and at the end of the 13th year you will have 52.
