Correct Answer: Rs. 6048

Solution : The selling price of an item is calculated as the cost price plus the profit.
The profit is calculated as a percentage of the cost price.
Given that the cost price of the cooler is Rs. 4800 and the profit percentage is 26%.
Profit percentage = $\frac{\text{Profit}}{\text{Cost price}}$ × 100
Profit = Cost price × $\frac{\text{Profit percentage}}{100}$ = 4800 × $\frac{26}{100}$ = Rs. 1248
Therefore, the selling price of the cooler is:
Selling price = Cost price + Profit = 4800 + 1248 = Rs. 6048
Hence, the correct answer is Rs. 6048.
