The Poisson ratios of soil sample 1 & 2 are $$\mu_{1}$$ and $$\mu_{2}$$ respectively and the coefficient of earth pressure at rest for soil sample 1 and 2 are $$K_{1} and K_{2}$$ respectively.If $$\frac{\mu_{1}}{\mu_{2}}$$= 1.5 and $$\frac{1-\mu_{1}}{1-\mu_{2}} $$=0.875 then $$\frac{k_{1}}{k_{2}}$$ will be
