Question

Cost of a price of a pen is 20. Selling price is 25. Find the gain percentage ​

Answer 1

Answer:

Let us assume that cost price(CP) of one pen be Rs1. So cost price of 25 pen will be Rs 25. According to question 20 pen will be sold at a price equal to cost price of 25 pen

Therefore SP of 20 pen = Rs 25

SP of 1 pen =(25/20)

profit =( SP of 1 pen—CP of 1pen) divide by CP(1pen)

%profit =profit*100

Apply this we will get 25%
