<output>156</output>
Rs 156 .   S.I. for 2 years= Rs (156 x x 2)= Rs 208.   Principal = Rs (1008 - 208)= 
<gadget id="calculator">(1008 - 208)</gadget>
<output>800</output>
Rs 800.   Now, P= 800, T= 2 and S.I. = 208.   Rate = (100 x S.I.) / (P x T) = [ (100 x 208)/(800 x 2)]% = 13%   Answer: 13%
<result>B</result>
