Mn has 25 electrons
2, 8 , 15
the 15 are as 3s---2, 3p---6, rest are in 4s and 3d...(2 others)
Mn++ has thus no unpaired electron

It's electronic configuration is:

1s2 2s2 2p6 3s2 3p6 3d5

3d subsell has five orbitals. So Mn++ has 5 unpaired electrons, one in each of the five orbitals, according to the Hund's rule.
