25%, Table = 10%)Total selling price of table and chair = Rs. 7500 (Profit: Chair = 10%, Table = 20%)Formula:Selling price = (100 + profit %)/100 × Cost priceCalculation:Let the cost price of table and chair be 100x and 100y respectivelyAccording to the question,125x + 110y = 7600⇒ 25X + 22y = 1520 ----(i)Also, 110x + 120y = 7500⇒ 11x + 12y = 750 ----(ii)From (i) and (ii), we get300y – 242y = 2030⇒ y = 35From (i), we getx = 30∴ Cost price of chair = 100x = Rs. 3000Cost price of table = 100y = Rs. 3500
