- C.
  
  4
- D.
  
  1
Correct Answer
D. 1

If n(A)=n(B),then A, B are called_________ sets.
- A.
  
  Equal
- B.
  
  Equivalent
- C.
  
  Disjoint
- D.
  
  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.

The difference between the length and breadth of a rectangle is 23 m. if its perimeter is 206 m, its area is
- A.
  
  1520 square meter
- B.
  
  2420 square meter
- C.
  
  2480 square meter
- D.
  
  2520 square meter
Correct Answer
D. 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.

If each side of a square is halved, the area of the new square is ______ the area of the original square
- A.
  
  One-ninth
- B.
  
  Double
- C.
  
  One-fourth
- D.
  
  Four times
Correct Answer
C. 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.
