Answer 2

Answer:

The gain percentage is 12.5% .

Step-by-step explanation:

Formula

$Gain\ percentage = \frac{Gain\times 100}{Cost\ price}$

As given

Purchase price of a ball pen is Rs. 4.50.

if four dozen ball pens were purchased at this rate and sold with a profit of Rs. 27 .

As one dozen contains 12 things .

Thus

Number of pens contains in 4 dozen = 4 × 12

                                                             = 48

Cost price of the 48 pens = Number of pens × Cost per pen

                                           = 48 × 4.50

                                           = Rs 216

$Gain\ percentage = \frac{27\times 100}{216}$

$Gain\ percentage = \frac{2700}{216}$

Gain percentage = 12.5%

Therefore the gain percentage is 12.5% .
