Question

A fruit seller bought 25 kg apples at 8 rs per kg AND 30 kg apples at 10 rs per kg at what rate per kg should he sell them to gain 21 percent

Answer 1

Dear Student,

​​​​​​Fruit Seller bought 25 kgs apples at 8 Rs/kg i.e. , for 25 * 8 = 200 Rs.
and bought 30 kg apples at 10 Rs/kg i.e., for 30*10 = 300 Rs.

So, the Cost Price of 55 kg apples (CP) = (200+300) Rs = 500 Rs.

Profit percent to be made after selling fruits = 21%
Profit = (Profit% / 100) * CP

Profit = (21 / 100 )* 500 = Rs. 105
Selling Price = Cost Price + Profit = (500 + 105) Rs.
Selling Price of 55 kg apples (SP) = Rs. 605

So, Selling price of 1 kg apple = Rs. ( 605/55) = Rs 11

Therefore, the fruit seller should sell the fruits at the rate of 11Rs per Kg to gain profit of 21%.
