Final answer:
To find the selling price, add the cost of the phone, repair cost, and profit percentage. The selling price is Rs 8046.
Step-by-step explanation:
To find the selling price of the mobile phone, we need to add the cost of the mobile phone, the repair cost, and the profit.
Step 1: Add the cost of the mobile phone (Rs 6890) and the repair cost (Rs 560):
6890 + 560 = 7450
Step 2: Calculate the profit by multiplying the total cost (7450) by 8% (0.08):
7450 * 0.08 = 596
Step 3: Add the profit to the total cost to get the selling price:
7450 + 596 = 8046
Therefore, the selling price of the mobile phone is Rs 8046.
