Correct Answer - Option 3 : Rs. 750
Given:
Cost price = Rs. 400 + Rs. 110 = Rs. 510
Discount = 15%
Profit = 25%
Formula used:
Marked Price(MP) = Selling Price(SP) + Discount
SP = Cost Price(CP) × (100 + profit%)/100
Calculation:
According to the question = Rs. 510
SP = 510 × (125/100) = Rs. 637.5
Let marked price be 100%
S.P = 100 - 15 = 85%
85% = 673.5
⇒ 100% = 673.5 × (100/85)
⇒ 100% = Rs. 750
∴ The marked price will be Rs. 750.
