(C) Given Banker's Discount $(B.D.)$ for $1.5$ years $= Rs.\, 837$.Therefore,$B.D.$ for $2$ years $= 837 	imes \frac{2}{1.5} = 837 	imes \frac{4}{3} = Rs.\, 1116$.True Discount $(T.D.)$ for $2$ years $= Rs.\, 900$.Sum $= \frac{B.D. 	imes T.D.}{B.D. - T.D.} = \frac{1116 	imes 900}{1116 - 900} = \frac{1116 	imes 900}{216} = Rs.\, 4650$.Since $B.D.$ is the Simple Interest $(S.I.)$ on the sum for the given time,$1116 = \frac{4650 	imes R 	imes 2}{100}$.$R = \frac{1116 	imes 100}{4650 	imes 2} = \frac{111600}{9300} = 12 \%$.Thus,the rate percent is $12 \%$.

The banker's discount on a sum of money for $1 \frac{1}{2}$ years is $Rs.\, 837$ and the true discount on the same sum for $2$ years is $Rs.\, 900$. The rate percent is:
