Answer 1

Step-by-step explanation:

His total profit percentage is (100/3) or 33 and 1/3 percentage.

4kg faulty weight=3.6kg actual or correct weight.

1kg faulty weight=.9kg correct weight.

So the person is selling at the price of Rs 60 per .9 kg weight.

1kg correct weight apples selling price=60/.9=200/3 Rs

His gain per kg=(200/3)-50=(50/3)rupees

His total profit percentage =

(profit per kg/C.P per kg)*100={(50/3)/50}*100=(1/3)*100=100/3=33 and1/3 percent.
