(C) Total quantity of cotton $= 500 \, kg$.Total cost price $(C.P.) = Rs. 9,000$.$10 \%$ of the cotton is spoiled,so the quantity of spoiled cotton $= 500 	imes 0.10 = 50 \, kg$.Remaining quantity of cotton $= 500 - 50 = 450 \, kg$.To earn a $10 \%$ profit,the total selling price $(S.P.)$ must be $110 \%$ of the cost price.Total $S.P. = 9,000 	imes 1.10 = Rs. 9,900$.Rate at which he should sell the remaining cotton $= \frac{	ext{Total } S.P.}{	ext{Remaining quantity}} = \frac{9,900}{450} = Rs. 22 \, 	ext{per } kg$.

$A$ trader buys $500 \, kg$ of cotton for $Rs. 9,000$. $10 \%$ of this cotton is spoiled due to rain. At what rate $(Rs./ kg)$ should he sell the rest to earn $10 \%$ profit?
