Question

Ashok purchased ballpoint pens at Rs 144 a dozen. He sold each pen for Rs 15. Find his gain or loss.​

Answer 1

Answer:

Profit per pen is 3 rs

& total profit is 36 rs

Step-by-step explanation:

1 dozen pens = 12 pens

∴ cost of one pen = 144/12

∴ cost of one pen = 12

∴ C.P. =12 rs

S.P = 15 rs

Profit = S.P - C.P

∴ Profit = 15 - 12

∴ Profit = 3 rs

∴ total profit = 12 × 3

∴ total profit = 36
