Question
A fruit seller sells apples at a profit of 20% and
oranges at a loss of 10%. If the ratio of apples to oranges sold is 3:2 and the overall profit is rupees 60, what is the total cost price of the fruits?Solution
Let the cost price of apples be 3x and oranges be 2x. Profit on apples = 20% of 3x = 0.6x. Loss on oranges = 10% of 2x = 0.2x. Net profit = 0.6x - 0.2x = 0.4x 0.4x = 60 x = 150. Total cost price = 3x + 2x = 750. =750
