Bavitaa Foundation Maths Quiz - 5

Explanation
If profit is a positive number, it means that there is a financial gain. In contrast, a loss represents a negative number in terms of finances. Therefore, the answer "Loss" is a negative number in this context.

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.

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.

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.

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.
