Conclusions:
I. All Aloo paratha is Gobi paratha.(True becasue All Aloo paratha is Matar paratha and All Matar paratha is Gobi paratha so obviously All Aloo paratha will be Gobi paratha)
II. No Aloo paratha is Mooli paratha.(True because No Gobi Paratha is Matar paratha and All Aloo paratha is Gobi paratha So obviously No Aloo paratha will be Mooli paratha)
III. Some Matar paratha is Aloo paratha.(True because All Aloo paratha is Matar paratha )
IV. Some Mooli paratha is not Aloo paratha.(when conclusion II is true which is No Aloo paratha is Mooli paratha so obviously Some Mooli paratha is not Aloo paratha...........Thats why this conclusion is also true)
