    "Question": "You are given two statements about a triangle: (1) The length of one side is 5 units. (2) The triangle is equilateral. Is the information sufficient to find the perimeter of the triangle?",
    "Answer": "A",
    "Explanation": "Since the triangle is equilateral, all sides are equal. Knowing one side is 5 units means all sides are 5 units, so the perimeter is 5 + 5 + 5 = 15 units. The data is sufficient.",
    "PictureURL": "https://upload.wikimedia.org/wikipedia/commons/thumb/4/4f/Equilateral_triangle.svg/1200px-Equilateral_triangle.svg.png",
    "OptionA": "Yes, the data is sufficient.",
    "OptionB": "No, the data is not sufficient.",

    "Question": "A rectangle has a length of 10 units. Statement (1): The width is 4 units. Statement (2): The area is 40 square units. Are these statements sufficient to find the perimeter of the rectangle?",
    "Answer": "A",
    "Explanation": "Statement (1) alone is sufficient because perimeter = 2(length + width) = 2(10 + 4) = 28 units. Statement (2) alone is also sufficient because area = length × width, so width = 40/10 = 4 units, which leads to the same perimeter calculation. Either statement alone is sufficient.",

    "Answer": "B",
    "Explanation": "Statement (2) alone is sufficient because 2x + 3 = 11 implies 2x = 8, so x = 4. Statement (1) alone is not sufficient because knowing x is an integer does not give its value. Therefore, only statement (2) is sufficient.",

    "Answer": "A",
    "Explanation": "Statement (1) alone is sufficient because speed = distance/time = 150/3 = 50 km/h, so time for 200 km = 200/50 = 4 hours. Statement (2) alone is sufficient because speed is given, so time = distance/speed = 200/50 = 4 hours. Each statement alone is sufficient.",

    "Explanation": "Let the number of oranges be x, then apples = 2x. Total fruits = x + 2x = 3x = 20, so x = 20/3 which is not an integer.
