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
