A trader bought 10 kg of apples for ₹405 out of which 1 kg of apples were found to be rotten. If he wishes to make a profit of 10%, at what rate should he sell the remaining apples per kg?

₹49.50

C.P. of 10 kg Apple = Rs.405

1 kg was rotten then

C.P. of 9 kg apple = Rs. 405

C.P. 1 kg Apple = \(\frac{405}{9}\) = Rs.45

S.P. to earn 10% profit = 45 × \(\frac{110}{100}\) = 49.5 Rs./kg
