Statements:
All plastics are glasses.
Some sponges are glasses.
All sponges are clothes.
All clothes are liquids.
Conclusions:
I. All liquids are sponges.
II. Some plastics are clothes.
III. All glasses are plastics.
IV. All liquids are clothes.
🎥 Video solution / Text Solution of this question is given below:
Analyze:
Plastics ⊆ Glasses
Sponges ⊆ Glasses
Sponges ⊆ Clothes
Clothes ⊆ Liquids
Now check conclusions:
I. All liquids are sponges → FALSE.
Liquids include many other things. No reverse relation.
II. Some plastics are clothes → FALSE.
Plastics ⊆ Glasses but no link to Clothes.
(No intersection shown).
III. All glasses are plastics → FALSE.
Only Plastics ⊆ Glasses, not reverse.
IV. All liquids are clothes → FALSE.
Given: All clothes ⊆ liquids, reverse is NOT true.
So none of the conclusions follow.
