Question

A man purchases 8 pens for rs.9 each.he sells 9 pens for rs.8 each. Find the profit or loss percentage of the person?

Answer 1

11.111 % (loss)

Step-by-step explanation:

cost price of 8 pens, if he bought 9 rs. each  = 8\times 9

CP = 72

And he sells 9 pens, each 8 rs.

Then selling price (SP) = 72

if he sells 9 pens then ,then he buy 9 pens.

CP of 9 pens = $9\times 9$

                       = 81  

Now , we find percentage,

CP = 81

SP = 72

Then,

= 81 - 72

= 9 ( loss)

Percentage of loss,

⇒ $\frac{9}{81} \times 100$

⇒ 11.111 % (loss)
