Question

Statements: All students are hardworking. No hardworking person is lazy. Conclusions: I. No student is lazy. II. Some hardworking persons are students. Which conclusion follows?

• A. Only conclusion I follows
• B. Only conclusion II follows
• C. Neither I nor II follows
• D. Both I and II follow

Hint:

Students inherit 'not lazy' from hardworking, and 'All students are hardworking' gives a 'Some' converse.

Answer 1

The Correct Option is D

The students circle lies inside hardworking, which lies entirely outside lazy; therefore students are outside lazy too (I true). The students circle is a part of the hardworking circle, so some hardworking persons are students (II true). Both follow.
