Question

A shopkeeper bought 4 dozen pens at the rate of Rs 15 per pen. 8 of the pens were stolen. At what
price should he sell each of the remaining pens to make a total profit of Rs 40?

Answer 1

4 dozen = 48 pens
Total price = 48*15
= ₹720
8 pens = 8*15
=₹120
720/120
=₹6
48-8=40
40/6
6.66
Each pen price
= ₹15+6.66
=₹21.66
So, each pen should be sold for ₹21.66

➼ 4 dozen = 48 pens

➪ Total price = 48 × 15 = 720

● 8 pens were stolen....

➪ So, the remaining pens are 40

➪ Let the selling price be x

➪ x = (720 + 40) ÷ 40

= 19 Rs.
