Hiii 
The electronic configueration of Mn^+4 is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1
so, you can clearly see that the number of unpaired electron is in 3d subshell and that is equal to 1.
Hope this helps

The actual electronic configuration of Manganese(Mn):
1s22s22p6,3s23p6,4s23d5
Mn4+: 1s2,2s22p6,3s23p6,3d3
Because due to tje presence of +ve charge first the electron removed from S-subshell till all charged are removed and then remaining from d-subshell.
