Correct option is
A
15 % profit
Total number of pens =300
Pens sold at no loss no profit =4300 = 75
Pens sold at 20% profit = 300−75=225
Let C.P. of one pen =Rs 1
C.P. of 225 pens =Rs 225
Total Profit =20%of225=10020×225=45
Total S.P. =225+45=270
Now, Including the pens sold at no profit and no loss.
Total CP =225+75=300
Total SP =270+75=345
Profit % =30045×100=15%
Hence, option 'A' is correct.
Concept:
Profit = Selling price - Cost price.
Discount = Selling price - profit - cost price
Discount % = Discount / Selling price × 100
Given:
Cost price of 1 pencil = Rs. 300
Selling price of 1 pencil = Rs. 400
Profit % = 30 %
Find:
We need to find the discount allowed by him.
Solution:
Profit = 30 % CP
Profit = 30 / 100 × ( 300) = Rs.90
Selling price = Rs.400
Discount = 400 - 300 - 90 = Rs.10
Percentage of discount = 10 / 400 × 100 = 2.5 %
Therefore, the percent discount he allows to his customers is 2.5 %.
