Question
Statements :  All woods are tables.
                       No table is a chair

Conclusion :  I.  At least some chairs are tables.
                        II.  No wood is a chair
 
  • A) if only conclusion I follows
  • B) if only conclusion II follows
  • C) if either conclusion I or conclusion II follows
  • D) if neither conclusion I nor conclusion II follows
  • E) if both conclusion I and conclusion II follow
Solution
B
No table is a chair (E) – converse – No chair is a table (E).
Hence conclusion I does not follow.
 
Again, All woods are tables (A) + No table is a chair (E) = A + E = E = No wood is a chair.
Hence conclusion II follows.

Hence, option B is correct.
