If a \(3\times 3\) matrix is filled with +1's and -1's such that the sum of each row and column of the matrix is 1, then the absolute value of its determinant is...

If x, y, z are positive real numbers such that \(x^{12} = y^{16} = z^{24}\), and the three quantities \(3\log_y x\), \(4\log_z y\), \(n\log_x z\) are in arithmetic progression, then the value of n is

Let the set \(P = \{2, 3, 4, \ldots, 25\}\). For each \(k \in P\), define \(Q(k)=\{x\in P \text{ such that } x>k \text{ and } k \text{ divides } x\}\). Then the number of elements in the set \(P-\bigcup_{k=2}^{25}Q(k)\) is
