A substance undergoes a series of chemical reaction as shown 
 $\mathrm{A}\stackrel{{\mathrm{K}}_1}{\to }\mathrm{B}\stackrel{{\mathrm{K}}_2}{\to }\mathrm{C}\stackrel{{\mathrm{K}}_3}{\to }\mathrm{D}$ with rate constant K₁ = sec^–1, K₂ = $\frac{\ln 2}{10}$sec^–1, 
K₃ = 20 ln 2 sec^–1. What will be the value of $\frac{\left[\mathrm{A}\right]}{\left[\mathrm{C}\right]}$ once steady state is obtained.
