The shopkeeper sold the earrings at the profit of 25%
and the cost price of earrings is Rs.3000. He earns x% profit on bracelet costing Rs.2500. If the overall profit on selling both earrings and bracelet is 30%, then find the value of x?Solution
Overall profit = 30/100 × (3000 + 2500) = 1650 Profit on Earrings = 3000 × 25/100 = 750 Profit on Bracelet = 1650 – 750 = 900 => x = (900/2500) × 100 => x = 36%
