Question

A man purchases 8 pens for rs.9 and sells 9 pens for rs.8, how much profit or loss does he make

Answer 1

Answer:

Step-by-step explanation:

8 pen =Rs 9

1 pen =Rs 9/8

Total CP for 1 pen is Rs 9/8

Sp of 9 pen = Rs 8

Sp of 1 pen= Rs 8/9

Total SP for 1 pen is Rs 8/9

Loss 9/8 - 8/9 = Rs 17/72 = 0.2361 Ans

Answer 2

The man makes loss of Rs. 0.236/- per pen.

The man purchases 8 pens for Rs. 9

∴ The cost of total 8 pens is Rs. 9

⇒ The cost of 1 pen is Rs. $\frac{9}{8}$

                                    = Rs. 1.125

So, one pen would have been cost him Rs. 1.125

Now, he sells 9 pens for Rs. 8

∴ The cost of total 9 pens is Rs. 8

⇒ The cost of 1 pen is Rs. $\frac{8}{9}$

                                   =  Rs. 0.889

He spent more money per pen in buying than in selling them.

∴ Amount of loss per pen = Rs. ( 1.125 - 0.089 )

                                          = Rs. 0.236/-

The amount of loss he faced per pen is Rs. 0.236/- .
