Question

Gopal purchased 8 dozen pens for rs 3024 and sold them at the rate of rs 36 per pen calculate his profit percent or loss percent on it.

Answer 1

cost price of 8 dozen pens = ₹ 3024

since , we know 1 dozen = 12

so then 8 dozen = 8 × 12 = 96 pens

cost price of 96 pens = ₹ 3024

selling price of 1 pen = 36

then Find the selling price of 96 pens :
----------------------------------

selling price of 96 pens = 96 × 36

= ₹ 3456

Find the profit :
---------------------

profit = selling price - cost price

profit = ₹ 3456 - ₹ 3024

profit = ₹ 432

Find the profit % :
------------------------

profit % = ( profit × 100 ) / cost price

profit % = ( 432 × 100 )/ 3024

= 43200 / 3024 = 14.2 % (approx.)

Answer : profit = 14.2%
