Let C.P. of article = Rs. 100
∴ Marked price = Rs. 120
On profit of 8% , Its S.P. = Rs. 108
∴ Discount = Rs. (120 – 108) = Rs. 12
∴ If discount be y%, then,120 × y = 12 100
Correct Option: C
Let C.P. of article = Rs. 100
∴ Marked price = Rs. 120

∴ Discount = Rs. (120 – 108) = Rs. 12
∴ If discount be y%, then,120 × y = 12 100 ⇒ y = 12 × 100 = 10% 120
