Two statements are given followed by four conclusions I, II, III and IV. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions can definitely be drawn from the given statements.Statements:
(A) No cow is a chair.
(B) All chairs are tables.
Conclusions:
I. Some tables are chairs
II. Some tables are cows
III. Some chairs are cows
IV. No table is a cow
Show Hint
When one relation is uncertain, conclusions often appear as “Either–Or”.
Step 1: From “All chairs are tables”, chairs are a subset of tables.
Step 2: From “No cow is a chair”, cows are completely separate from chairs.
Step 3: Cows may or may not be tables. Hence either:
- Some tables are cows, or
- No table is a cow
Step 4: Thus either II or IV must follow.
