Problema Solution
a vendor buys lemons at `25per dozen and sells them at the rate of 5 for `12 .find the gain or loss per cent.
Answer provided by our tutors
The profit is equal to the amount the lemons are sold for minus the amount the vendor paid for them. We will call the price in dollars. Therefore, we can write:
profit per lemon=($12/5)-($25/12)
profit per lemon=($19/60) or $.32 per lemon
The percentage gain or lost will be equal to [(profit per lemon)/(paid per lemon)]*100. Therefore, we can write:
percentage= ($19/60)/($25/12) *100= 15.2%
15.2% is the percent gained.
