Directions to Solve
In each question below are given two statements followed by two conclusions numbered I and II. You have to take the given two statements to be true even if they seem to be at variance from commonly known facts. Read the conclusion and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts.
Give answer:
- (A) If only conclusion I follows
- (B) If only conclusion II follows
- (C) If either I or II follows
- (D) If neither I nor II follows and
- (E) If both I and II follow.
2.
Statements: All bags are cakes. All lamps are cakes.
Conclusions:
- Some lamps are bags.
- No lamp is bag.
Answer: Option
Explanation:
Since the middle term 'cakes' is not distributed even once in the premises, no definite conclusion follows. However, I and II involve only the extreme terms and form a complementary pair. So, either I or II follows.

Cake is the pool, could be composed of bags and lamps only or more.
All bags are part of the pool.
All lamps are also part of the pool.
If some lamp are bags, it makes the second statement invalid and.
If no lamp is a bag, making statement one invalid.
So only one can be the answer, so either.
All bags are part of the pool.
All lamps are also part of the pool.
If some lamp are bags, it makes the second statement invalid and.
If no lamp is a bag, making statement one invalid.
So only one can be the answer, so either.

Statements: All bags are cakes. All lamps are cakes.
Means Some lamps may be bags or may not be bags.
If "may be bag" then conclusion "II. No lamp is bag" will not be valid. Conclusion 1 will only valid.
If "may not be bags" then conclusion "I. Some lamps are bags" will not valid. Only conclusion 2 will valid.
So the answer is C] Either I or II follows.
Means Some lamps may be bags or may not be bags.
If "may be bag" then conclusion "II. No lamp is bag" will not be valid. Conclusion 1 will only valid.
If "may not be bags" then conclusion "I. Some lamps are bags" will not valid. Only conclusion 2 will valid.
