$Ag\left( s \right)\left| {AgBr\left( s \right)\,\left| {B{r^ - }\left( {0.01\,M} \right)} \right|\,\left| {{I^ - }\left( {0.02\,M} \right)} \right|\,AgI\left( s \right)} \right|Ag\left( s \right)$
the correct information is
[Given : $K_{sp}\,\left( {AgBr} \right) = 4 \times {10^{ - 13}}$ ,
$K_{sp}\,\left( {AgI} \right)$ $ = 8 \times {10^{ - 17}},\frac{{2.303\,RT}}{F} = 0.06\,V,\,\log \,2 = 0.3]$
$Zn^{2 + }(aq.) + 2e⇔ Zn(s)$; $→$ $ -0.762$
$Cr^{3 + }(aq) + 3e ⇔ Cr(s)$; $→$ $-0.740$
$2H^ +(aq) + 2e⇔ {H_2}(g)$; $→$ $0.00$
$Fe^{3+}(aq) + e ⇔ Fe^{2+}(aq)$; $→$ $0.770$
