Step 1: Let cost price (CP) = \(x\)
Step 2: Loss of 5% at selling price (SP) 475
Loss means SP < CP
\[ SP = CP - 5% \text{ of } CP = 0.95x = 475 \] \[ x = \frac{475}{0.95} = 500 \] So, CP = Rs 500
Step 3: To gain 5%, new SP should be
\[ SP = CP + 5% \text{ of } CP = 1.05 \times 500 = 525 \] Thus, Option (B) Rs 525 is correct.
