Solubility product

In 1 L saturated solution of AgCl [$K_{sp}$(AgCl) $=1.6\times10^{-10}$], 0.1 mol of CuCl [$K_{sp}$(CuCl) $=1.0\times10^{-6}$] is added. The resultant concentration of $\ce{Ag+}$ in the solution is $1.6\times10^{-x}$. The value of "$x$" is

Solubility product constants ($K_{sp}$) of salts of types MX, MX₂ and M₃X at temperature 'T' are $4.0\times10^{-8}$, $3.2\times10^{-14}$ and $2.7\times10^{-15}$, respectively. Solubilities (mol dm⁻³) of the salts at temperature 'T' are in the order
