This equation is not balanced. To balance it, we need to make sure that the number of each type of atom is the same on both sides of the equation.

Here is the balanced equation:

2KMnO4 + 3MnSO4 + 4H2O -> K2MnO4 + 3$MnO2$ + 2H2SO4

Now, the number of each type of atom is balanced on both sides of the equation.
