D Correct answer
Explanation

Area of one chair = 3*4 = 12 sq ft. Total area for 50 chairs = 600 sq ft. Area of one table = 4*6 = 24 sq ft. Total area for 10 tables = 240 sq ft. Percent more = ((600 - 240) / 240) * 100 = (360 / 240) * 100 = 150%.

AI explanation

The area of one chair is calculated by multiplying its length by its breadth, which gives 3 feet times 4 feet equal to 12 square feet. Since there are 50 chairs, the total area covered by chairs is 50 times 12, resulting in 600 square feet. The area of one table is 4 feet times 6 feet equal to 24 square feet, and for 10 tables, the total area is 240 square feet. Using the percentage difference formula, ((600 - 240) / 240) times 100 equals 150 percent.
