To Aarti Gupta ji: the I can see that O.S. is +VI and +IV. How do you justify +V and +III?

Aratri Gupta Ji has correctly stated the oxidation state of the sulphur atoms as +5 & +3 and not +6 and +4 as you shouldn't include the S-S bond while calculating oxidation state!(A bond is only changes the oxidation state when it is polar but here since both the bonded atoms are same the bond is a covalent and not an ionic one!)
