Correct Answer - Option 5 : 1286.40

**GIVEN:**

⇒ Discount % = 27.27% = 3/11.

⇒ Profit = 12.5% = 1/8

⇒ The difference of Cost price and Selling price = Rs. 160.80

**FORMULA USED:**

⇒ C.P = {100/(100 + gain %)] × S.P

⇒ S.P – C.P = Gain

**CALCULATION:**

⇒ Let cost price = Rs. x

⇒ Profit = 12.5%

⇒ Selling price = x × (112.5/100)

⇒ S.P = 1.125x

⇒ Discount = 27.27%

⇒ Selling price = Marked price × (72.73/100)

⇒ 1.125x = Marked price × (72.73/100)

⇒ Marked price = 1.54x

⇒ Now, Gain = S.P – C.P

⇒ 1.125x – 1x = Rs. 160.80

⇒ 0.125x = Rs. 160.80

⇒ x = Rs. 1286.40
