A person purchased 78 kg of rice at the rate of Rs. 50 per kg He sold 36 kg at a profit of 21%. At what rate per kg should he sell the remaining rice to obtain an overall profit of 28% ?

Answer»

67 kg



Cost PRICE = 78 x 50 = 3900
For 28% PROFIT, selling price = 3900 x 1.28 = 4992
Cost price of 36 kg = 36 x 50 = 1800
Selling price of 36 kg = 1800 x 1.21 = 2178
Remaining rice = 78 - 36 = 42 kg
Selling price of the remaining rice shhould be 4992 - 2178 = 2814
∴ Rate per kg = 2814/42 = 67
ie RS. 67 kg
