Detailed Solution

Given, that 16 dozen ball pens are bought, and sold at loss same as selling price(SP) of 8 ball peens.
Loss percentage is,

loss % = loss C P (100)

Number of pens bought

= 1612

⇒ 192

Let the SP of one pen be Rs.x.
Therefore, SP of 192 pens

= 192 x

SP of 8 pens

= 8 x

It is given that SP of 8 pens are equal to the loss on selling 192 pens.
So,

loss = CP − SP ⇒ 8 x = 576 − 192 x ⇒ 200 x = 576 ⇒ x = 2.88

Therefore,

loss = 8 2.88 ⇒ loss = 23.04

Now, loss percentage is,

loss % = loss CP (100) ⇒ 23.04 (100) 576 ⇒ 4 %

Hence, the loss percent is 4%.
Therefore, option (3) is correct.
