Correct answer: A

Goods received = 3 notebooks + 1 pen, worth 3 × ₹60 + ₹20 = ₹200.
Amount paid = ₹180, so the discount is ₹20.
Discount % = $\frac{20}{200} \times 100 = 10\%$ .

Worth noting

The free item is cheaper than the items bought, so '1 in 4 free' (25%) does not apply. $11\frac{1}{9}\%$ divides by the amount paid instead of the value received.
