Correct Answer - Option 1 : 20% loss
Given:
The marked price of book is 60% above the cost price.
Discounts is 50%
Concept Used:
Discount is always given on the marked price.
Formula used:
SP = MP × (100 - D)/100
Here, SP → Selling price, D → Discount
Calculation:
Let the cost price of the book be Rs. 100x
So, marked price = 160% of 100x = Rs.160x
As, discount is of 50%
∴ Selling price = \(160x × {50 \ \over 100}\) = Rs.80
⇒ Loss = C.P - S.P = 100x - 80x = 20x
∴ Loss % = \({20x \ \over 100x} × 100\) = 20%
∴ The loss percent in selling the book at 50% discount is of 20%
