Question
The shopkeeper sold the earrings at the profit of 25%
and the cost price of earrings is Rs.3600. He earns x% profit on bracelet costing Rs.3000. If the overall profit on selling both earrings and bracelet is 30%, then find the value of x?Solution
Overall profit = 30/100 × (3600 + 3000) = 1980 Profit on Earrings = 3600 × 25/100 = 900 Profit on Bracelet = 1980 – 900 = 1080 => x = (1080/3000) × 100 => x = 36%
