Correct Answer - Option 3 : 75%
Given:
The ratio of cost price to marked price of a product is 4 : 7.
Formula used:
Percentage profit = (SP – CP) × 100 / CP = Profit × 100 / CP
Calculation:
∴ CP : MP = 4 : 7
Now, Discount is always given on marked price, so if there is no discount then Marked price = Selling price = SP
Thus, CP : SP = 4 : 7
That is, Profit = SP – CP = 7 – 4 = 3
∴ Profit% = [Profit × 100] / CP = [3 × 100] /4 = 75%
