Redox Reactions and Electrochemistry: JEE Main 2021 Chemistry question

Consider the cell at 25$^\circ$C Zn | Zn²⁺ (aq), (1M) || Fe³⁺ (aq), Fe²⁺ (aq) | Pt(s) The fraction of total iron present as Fe³⁺ ion at the cell potential of 1.500 V is x $\times$ 10^$-$2. The value of x is ______________. (Nearest integer) (Given : $E_{F{e^{3 + }}/F{e^{2 + }}}^0 = 0.77V$, $E_{Z{n^{2 + }}/Zn}^0 = - 0.76V$)
