Question

A fruitseller buys 100 kg apples at the rate of 20 per kg. He sold of the
apples at a loss of 7%. At what rate must he sell the remaining apples to make a
profit of 15% on the sale of all the apples?​

Answer 1

Cost of 100kg apples = 2000.

Vendor sold 40kg at a 7% loss. The cost of 40kg apples is 800. And with 7% loss, vendor got back = 800*0.93 = 744.

So vendor sold 40kg apples at 744 with 7% loss.

And a 15% profit on total cost of 2000 is, 2000*1.15= 2300.

So to get an overall 15% profit, vendor should sell remaining 60kg apples for a price of, 2300–744 = 1556.

Therefore price of each of remaining 60kg apples should be 1556/60 = 25.94 ~ 26 per kg.
