Find the cost of 1 pen:

12 pens = Rs 40

1 pen = 40 ÷ 12 = Rs 10/3

Find the selling price of 1 pen:

8 pens = Rs 24

1 pen = 24 ÷ 8 = Rs 3

Find the profit / loss :

Cost Price > Selling Price ⇒ It is a loss

Loss = 10/3 - 3 = Rs 1/3

Find the loss percentage:

Loss percentage = (1/3 ÷ 10/3) x 100

Loss percentage = 10%

Answer: The loss is 10%
