Final answer:
The selling price of the pen drive, after a 5% profit on the cost price of Rs 1200, is calculated to be Rs 1260.
Step-by-step explanation:
The question involves finding the selling price of a pen drive which was purchased at Rs 1200 and sold at a profit of 5%.
To calculate the selling price, we first determine the amount of profit earned by using the formula: Profit = (Profit percentage / 100) × Cost price.
Plugging in the values, we have:
Profit = (5 / 100) × 1200 = 0.05 × 1200 = Rs 60.
To find the selling price, we add the profit to the cost price:
Selling Price = Cost Price + Profit
Selling Price = Rs 1200 + Rs 60 = Rs 1260.
Therefore, the selling price of the pen drive is Rs 1260.
