Rs380

Rs460

Rs360

Rs420

- Let the cost price of the book be Rs x.

- Selling at Rs 450 provides a profit of (450 - x).

- Selling at Rs 390 results in a loss of (x - 390).

- Given the profit and loss amounts are equal: 450 - x = x - 390.

- Solving the equation: 450 + 390 = 2x.

- So, 840 = 2x, which gives x = Rs 420.

- Option 1: Rs 380 is incorrect since it does not satisfy the equation.

- Option 2: Rs 460 is incorrect as it makes the selling prices yield inexplicable results.

- Option 3: Rs 360 is incorrect for the same reason as option 1.

- Option 4: Rs 420 is the correct answer.
