To make a 10% profit even after giving 4% discount, the bedsheet must be marked at Rs. 550.

Quick explanation

  • Cost price (CP) = Rs. 480
  • Profit desired = 10% of 480 = 480×10100=48480\times \frac{10}{100}=48480×10010​=48 → Selling price (SP) = 480 + 48 = Rs. 528
  • A 4% discount is given on the marked price (MP), so the customer pays 96% of MP:
    SP=96% of MP⇒528=96100×MP\text{SP}=96%\text{ of MP}\Rightarrow 528=\frac{96}{100}\times \text{MP}SP=96% of MP⇒528=10096​×MP
  • So,
    MP=528×10096=550\text{MP}=\frac{528\times 100}{96}=550MP=96528×100​=550

Therefore, the marked price should be Rs. 550.
