Answer 2

Answer:

His profit percent = 50 %

Step-by-step explanation:

Given,

Cost Price of a dozen Pen = Rs 120

∴ CP of a pen = Rs 120/12 = Rs 10

Selling Price ( SP ) of a Pen = Rs 15

Here, SP > CP

That means there is profit.

Now,

Profit Percent = $\frac{SP-CP}{CP} *100$

                             = $\frac{15-10}{10} *100$

                             = $\frac{5}{10}*100$

                             = 50 %

Therefore,

His profit percent = 50 %
