Answer 1

Answer:

Profit is 20 %.

Step-by-step explanation:

A man sold 12 dozens of knives for rupees 60 .

The cost price of Per dozen is re 1 less than the selling price of Per dozen.

so Per dozen knives,

                               $S.P.-C.P.=1\\ \\ Profit=1$

For 12 dozens , Profit=12 Rupees

                                  $Percentage profit=(\frac{profit}{c.p} ) \cdot 100\\ \\ Percentage profit=\frac{12}{60} \cdot 100\\ \\ =20$
