Pd(0) will be in zero oxidation state as the (t-Bu3P)2Pd is a neutral ligand so it won’t contribute towards
the oxidation state of central atom Pd.
In the case of TiCl3, three Cl atoms will give 3 electrons and will make the oxidation state of Ti as +3.
X - 3 = 0
X = +3.
In the last case, the oxidation state of Ni will be +2 as the PPh3 and CO are neutral ligands and the oxygen will give one and C will give 1, overall making the oxidation state of Ni as +2.
