Question

By selling 60 pens a shopkeeper gain the cp of 15 pen. If he bought 20 pens in rs36. Find the sp of one pen

Answer 1

Step-by-step explanation:

$\huge\underline\green{Hola Mate,}$

CP of 20 pens = ₹36

CP of 1 pen = ₹36/20

CP of 15 pens = ₹36/20×15 = ₹27

CP of 60 pens = 27×60/15 = ₹108

Given that,

By selling 60 pens a shopkeeper gain the cp of 15 pen

So, By selling 60 pens the shopkeeper gained ₹27

Profit = ₹27

CP = ₹108

SP = CP+profit = 108+27 = ₹135

Then, SP of one pen = 135/60 = ₹2.25
