Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
I. No B is L.
II. No C is B.
Conclusions:
I. Some L are C.
II. Some B are C.
Option 1: Both conclusions I and II follow
Option 2: Only conclusion I follows
Option 3: Neither conclusion I nor II follows
Option 4: Only conclusion II follows
Correct Answer: Neither conclusion I nor II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions:
Conclusions (I):
Some L are C - In the above diagram it is clearly shown that circles of L and C are independent. It doesn't define any relation between them. So, this conclusion doesn't follow.
Conclusion (II):
Some B are C - In the above diagram it is clearly shown that a relation of no is given between B and C and if it is clear that no B are C or vice versa so some B are C is not true and this conclusion doesn't follow.
So, neither I nor conclusion II follows. Hence, the third option is correct.
