(D) The true discount is the simple interest on the present worth.Present Worth $(PW) = 	ext{Amount} - 	ext{True Discount} = Rs. 161 - Rs. 21 = Rs. 140$.Time $(T) = 2 	ext{ years } 6 	ext{ months} = 2.5 	ext{ years} = \frac{5}{2} 	ext{ years}$.True Discount $(TD) = \frac{PW 	imes R 	imes T}{100}$.$21 = \frac{140 	imes R 	imes 5}{100 	imes 2}$.$21 = \frac{700 	imes R}{200} = 3.5 	imes R$.$R = \frac{21}{3.5} = 6 \%$.Therefore, the rate of interest is $6 \%$.

If the true discount on $Rs. 161$ due for $2$ years and $6$ months is $Rs. 21$, then find the rate of interest (in $\%$).
