A shopkeeper allows 18% discount on the marked price of an article and still makes a profit of 23%. If he gains ₹18.40 on the sale of the article, then what is the marked price of the article?

₹ 120 ₹ 125 ₹ 140 ₹ 146

₹ 120

CP × 23% = 18.40           CP = 80           SP = 80 + 18.40 = 98.40            MRP × 82% = 98.40            MRP = 120
