Question

(b) A shopkeeper bought 50 pens for 100. He then sold each pen for 2.5 Find his profit or loss.​

Answer 1

Step-by-step explanation:

Shopkeeper bought each pen at 2 rupees (100/50)

He sold each pen for 2.5, after selling 100 pens, he'd have made 250 rupees.

He bought at 100 and sold at 250, so it's profit. Therefore the profit amount = 250-100 = 150 rupees.
