A trader buys 500 kgs 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?
Cotton left = 500 - 10% 0f 500 = 500 - 50 = 450kg
To get 10% profit, SP = 9000 + 10% of 9000 = 9000 + 900 = 9900/-
SP price/kg = 9900/450 = 22
So the answer is option C.
