Answer» $\begin{matrix} Column I & Column II (A) & If the roots of the equation & (P) & 7 x^{3} - 9 x^{2} + 26 x - k = 0 are positive and in A.P., then k is equal to (B) & If the roots of the equation & (Q) & 11 x^{3} - 14 x^{2} + k x - 64 = 0 are positive and in G.P., then k is equal to (C) & If the roots of the equation & (R) & 24 6 x^{3} - k x^{2} + 6 x - 1 = 0 are positive and in H.P., then k is equal to (D) & The harmonic mean for the roots of & (S) & 26 equation x^{3} - 11 x^{2} + 3 x - 26 = 0 is (T) & 56 \end{matrix}$ Which of the following is the only CORRECT combination?
