and the cost price of earrings is Rs.1800. He earns x% profit on bracelet costing Rs.1500. If the overall profit on selling both earrings and bracelet is 20%, then find the value of x?Solution
Overall profit = 20/100 × (1500 + 1800) = 660 Profit on Earrings = 1800 × 15/100 = 270 Profit on Bracelet = 660 – 270 = 390 => x = (390/1500) × 100 => x = 26%
