MnO^-_4(aq) + Y + 5Fe²⁺_(aq) → Mn²⁺_(aq) + 5Fe²⁺_(aq) + 4H₂O^(l)
In the equation above, Y is

the equation is wrong
it is supposed to be MnO4- +Y + 5Fe2+
=Mn2+ +4H2O +5Fe3+
Therefore,you will have to balance both equation in the LHS= -1+10=9
RHS=2+15=17
LHS=RHS
9+Y=17
therefore Y =8+
I hope you understand

The question is wrong.
the 'Iron part' of the question should be 5Fe²+ --------> 5Fe³+ and Not 5Fe²+ --------> 5Fe²+

@Olanipekun i actually multiplied +2 and 5 look closely to the LHS ,I hope u have understood it
