Answer» Correct Answer - Option 1 : 807.50 Given: Marked price: Rs. 1,250 Discount offered 5%, 15% and 20% Formula used: S.P= M.P × {(100 - d1)/100} × {(100 - d2)/100} × ......× {(100 - dn)/100} M.P = Marked price S.P = Selling price d1,d2....dn = discount% Calculation: We need to find S.P S.P = M.P × {(100 - d1)/100} × {(100 - d2)/100} × ......× {(100 - dn)/100} ⇒ S.P = 1250 × {(100 - 5)/100} × {(100 - 15)/100} × {(100 - 20)/100} ⇒ S.P = 1250 × (95/100) × (85/100) × (80/100) ⇒ S.P = 807.50 ∴ The selling price is Rs. 807.50

Answer» Correct Answer - Option 1 : 807.50

Given:

Marked price: Rs. 1,250

Discount offered 5%, 15% and 20%

Formula used:

S.P= M.P × {(100 - d1)/100} × {(100 - d2)/100} × ......× {(100 - dn)/100}

M.P = Marked price

S.P = Selling price

d1,d2....dn = discount%

Calculation:

We need to find S.P

S.P = M.P × {(100 - d1)/100} × {(100 - d2)/100} × ......× {(100 - dn)/100}

⇒ S.P = 1250 × {(100 - 5)/100} × {(100 - 15)/100} × {(100 - 20)/100}

⇒ S.P = 1250 × (95/100) × (85/100) × (80/100)

⇒ S.P = 807.50

∴ The selling price is Rs. 807.50
