Standard electrode potential for $\displaystyle \mathrm{Sn}^{4+} / \mathrm{Sn}^{2+}$ couple is +$\displaystyle 0.15$ V and that for the $\displaystyle \mathrm{Cr}^{3+} / \mathrm{Cr}$ couple is -$\displaystyle 0.74$ V. These two couples in their standard state are connected to make a cell. The cell potential will be :
Official answer
(3)
+$\displaystyle 0.89$ V
