Question
The cost prices of a table and a chair are in the ratio
3:5 respectively. If the seller earned a profit of 15% on the table and an overall profit of 20%, find his profit percentage on the chair.Solution
ATQ, Let the cost price of the table be Rs. 300x and the chair be Rs. 500x. Profit on the table = 300x × 0.15 = Rs. 45x. Overall profit = (800x) × 0.2 = Rs. 160x. So, profit on the chair = 160x – 45x = Rs. 115x. Percentage profit on the chair = (115x/500x) × 100 = 23%.
