Answer 2

Let, Cost Price = x

Selling Price = Y

Then, 12x = 15y

Let Cost price (x) of 1 pen =Rs. 1

Then, cost price of 12 pens = Rs. 12

i.e. 12=15y => y = 12/15

=> 0.8 i.e. Cost price (x) = 1 ,

and selling price (y) = 0.8

As cost price is greater then selling price,

hence there is loss.

Loss = Cost price - selling price => 1 - 0.8 = 0.2

Percentage loss =20%
