Correct Answer - Option 1 : Rs. 1056

**Given:**

Profit percentage = 10%

Selling price of a mobile = Rs. 1320

Loss percentage = 12%

**Formula Used:**

C.P = S.P × {100/(100 + P%)}

S.P = C.P × {(100 - L%)/100}

Where C.P = Cost Price, S.P = Selling Price, P% = Profit Percent, L% = Loss Percent

**Calculation:**

(S.P)_{1} = Rs. 1320

C.P = (S.P)_{1} × {100/(100 + P%)}

⇒ 1320 × {100/(100 + 10)}

⇒ 1320 × {100/110}

⇒ 1320 × (10/11)

⇒ 1200

Cost price of a mobile = Rs. 1200

Again,

(S.P)_{2} = C.P × {(100 - L%)/100}

⇒ 1200 × {(100 - 12)/100}

⇒ 1200 × (88/100)

⇒ 12 × 88

⇒ 1056

**∴ Aman will sell the mobile for Rs. 1056 to suffer 12% loss.**
