- Let the cost price of each pen = ?1.

- Total cost for 600 pens = ?600.

- 480 pens were sold for ?600 (price of all 600 pens), so selling price per pen = ?600/480 = ?1.25.

- 100 pens were sold at 10% higher rate than ?1.25, so at ?1.25 × 1.10 = ?1.375 per pen.

- Selling price for 100 pens = 100 × ?1.375 = ?137.5.

- The remaining 20 pens were sold at cost price = 20 × ?1 = ?20.

- Total selling price = ?600 + ?137.5 + ?20 = ?757.5.

- Profit = ?757.5 – ?600 = ?157.5.

- Profit percentage = (?157.5/?600) × 100 = 26.25%
