Statements: Some TVs are laptops. Some laptops are mobiles. Conclusions: I. No mobile is TV. II. All mobiles are TV. Which conclusion logically does not follow?

1. Either conclusion I or II
2. Neither conclusion I nor II
3. Both conclusion I and II
4. Only conclusion I

Correct answer: Both conclusion I and II

Solution

From "some TVs are laptops" and "some laptops are mobiles," we only know that TVs, laptops, and mobiles each have some overlap with laptops. No definite conclusion about the relation between TVs and mobiles can be drawn. Hence both given conclusions do not follow.
