Question

A potato seller purchased 80 kg of potatoes from a seller . During his retail selling 5 kg of potatoes got rotten and were thrown out. At what rate per kg should he sell the remaining potatoes so as earn a profit of 10% on the whole?​

Answer 1

Answer:

Step-by-step explanation:

Let C & S denote cost-price & selling price per kg of potatoes.

Hence from above data we get following relation,

75*S = (1 + 10/100)*80*C

or 75*S = (11/10)*80*C

or S = (88/75)*C

or S = (1 + 13/75)*C

or S = (1 + 13*4/3/100)*C

or S = (1 + 17.33/100)*C

Therefore it is evident from above that to earn a profit of 10% on the whole,

the seller should sell the remaining (80 - 5 =) 75 kg potatoes

at a price that is 17.33% higher than the purchased price per kg.
