    If n(A)=n(B),then A, B are called_________ sets. 

    • Equal

    • Equivalent

    • Disjoint

    • Overlapping

    Correct Answer
    A. Equal
    Explanation
    If n(A) = n(B), it means that the number of elements in set A is equal to the number of elements in set B. Therefore, A and B are called "Equal" sets.

     If each side of a square is halved, the area of the new square is ______ the area of the original square

    • One-ninth

    • Double

    • One-fourth

    • Four times

    Correct Answer
    A. One-fourth
    Explanation
    When each side of a square is halved, the resulting square has sides that are half the length of the original square. Since the area of a square is calculated by multiplying the length of one side by itself, halving the length of each side would result in the area being one-fourth of the original square. Therefore, the correct answer is one-fourth.

     The degree of polynomial ax-c  is     

    • 9

    • 5

    • 4

    • 1

    Correct Answer
    A. 1
    Explanation
    The degree of a polynomial is determined by the highest power of the variable in the polynomial. In this case, the polynomial is ax-c, which has a variable raised to the power of 1. Therefore, the degree of the polynomial is 1.

    The difference between the length and breadth of a rectangle is 23 m. if its perimeter is 206 m, its area is

    • 1520 square meter

    • 2420 square meter

    • 2480 square meter

    • 2520 square meter

    Correct Answer
    A. 2520 square meter
    Explanation
    Let's assume that the length of the rectangle is L and the breadth is B. According to the given information, L - B = 23 and the perimeter (P) is 206. The formula for the perimeter of a rectangle is P = 2(L + B). Substituting the given values, we get 206 = 2(L + B). Simplifying this equation, we find that L + B = 103. Now we have a system of equations: L - B = 23 and L + B = 103. Solving this system, we find that L = 63 and B = 40. The area (A) of a rectangle is given by the formula A = L * B. Substituting the values, we get A = 63 * 40 = 2520 square meters.
