Redox Reactions and Electrochemistry: JEE Main 2007 Chemistry question

The cell, Zn | Zn²⁺ (1M) || Cu²⁺ (1M) | Cu($E_{cell}^o$ = 1.10V) was allowed to be completely discharged at 298 K. The relative concentration of Zn²⁺ to Cu²⁺ $\left[ {{{\left[ {Z{n^{2 + }}} \right]} \over {\left[ {C{u^{2 + }}} \right]}}} \right]$ is
