In a chemical reaction, $\displaystyle \mathrm{A}+2 \mathrm{~B} \xrightleftharpoons{\mathrm{K}} 2 \mathrm{C}+\mathrm{D}$, the initial concentration of B was $\displaystyle 1.5$ times of the concentration of A, but the equilibrium concentrations of A and B were found to be equal. The equilibrium constant(K) for the aforesaid chemical reaction is :
