2 moles each of A and B were taken in a flask at some temperature so as to establish the following equilibrium $A+B\rightleftharpoons 2D$ It was observed that $\frac{1}{3}$ of A has reacted. After attainment of equilibria 2 mole of C was added which caused establishment of another equilibria $B+C\rightleftharpoons E+D$ If at new equilibria mole fraction of E is $\frac{1}{6}$, then calculate % of A dissociated after both equilibria has established. Given: $\sqrt{61}=7.81$. Give answer after multiplying by 100.
