1.	List I has four entries and List II has five entries. Each entry of List I is to be matched with one entry of List II. List IList II (A)The minimum value of ab if roots ofx3−ax2+bx−2=0 are positive, is(P)36(B)The number of quadrilateral formed in an octagon having two sides common(Q)24with the octagon, is(C)If 2nC4, 2nC5 and 2nC6 are in A.P.,then the value of 2n is (R)18(D)The value of 72sinπ18sin5π18sin7π18 is(S)14(T)9 Which of the following is the only CORRECT combination?
Answer» $List I$ has four entries and $List II$ has five entries. Each entry of $List I$ is to be matched with one entry of $List II .$ $\begin{matrix} List I & List II (A) & The minimum value of a b if roots of x^{3} - a x^{2} + b x - 2 = 0 are positive, is & (P) & 36 (B) & The number of quadrilateral formed in an octagon having two sides common & (Q) & 24 with the octagon, is (C) & If^{2 n} C_{4},^{2 n} C_{5} and^{2 n} C_{6} are in A . P ., then the value of 2 n is & (R) & 18 (D) & The value of 72 sin \frac{π}{18} sin \frac{5 π}{18} sin \frac{7 π}{18} is & (S) & 14 (T) & 9 \end{matrix}$ Which of the following is the only CORRECT combination?
