Question

A shop keeper 10rs price sold 12 pen he get profit 3 pens cost price.how much one pen s price

Answer 1

Answer:

Let the Cost Price for 1 pen be Rs.100

So, Total Cost Price = 100 *14 = 1400

Selling Price for 10 pens is equal to cost of 14 pens

Therefore, Total Selling Price for 10 pens = 1400

so, SP for 1 pen = 1400/10 = 140

Profit on 1 pen = SP - Cost Price = 140–100 = 40

Profit on 1 pen = 40

Percentage Profit = Profit / Cost *100

% Profit/ Gain = 40/100*10 = 40%

Final Answer = 40%
