With KMnO4 and K2CrO4

10 will first get oxidised to aldehyde and then to carboxylic acid

but if PCC is used then rxn stops after formation of aldehyde

 

20 will first get oxidised to ketone and then to carboxylic acid with

lesser number of carbon atoms as that of starting reactant

 

However 30 will not get directly oxidised. Firstly it will loose water

and then ozonolysis will occur formining 2 products, Out of which

both will oxidise. One forming Carboxylic acid and other bi products
