$1\,L$ Solution $( X )+ AgNO _3$ solution (excess) $\rightarrow Y$
$1\,L$ Solution $( X )+ BaCl _2$ solution (excess) $\rightarrow Z$
The number of moles of $Y$ and $Z$ respectively are

Cu+ → Cu2+ + Cu
3MnO4– + 4H+ → 2MnO4– + MnO2 + 2H2O
2KMnO4 → K2MnO4 + MnO2 + O2
2MnO4– + 3Mn2+ + 2H2O → 5MnO2 + 4H+
