Answer 2

The profit% is 5%

Step-by-step explanation:

Cost price of 9 pens = Rs.10

Cost price of 1 pen =$\frac{10}{9}$

Selling price of 6 pens = Rs.7

Selling price of 1 pen =$\frac{7}{6}$

SP>CP

So, Profit

Profit% =$\frac{SP-CP}{CP} \times 100$

Profit% =$\frac{\frac{7}{6}-\frac{10}{9}}{\frac{10}{9}} \times 100 = 5\%$

Hence The profit% is 5%
