Question

In each group of questions below are two/three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two/three statements, disregarding commonly known facts. Give answer
Statements: No note is a coin.
Some coins are metals.
All plastics are notes.
Conclusions: I. No coin is plastic.
II. All plastics being metals is a possibility.

• A. if only conclusion I follows.
• B. if only conclusion II follows.
• C. if either conclusion I or conclusion II follows.
• D. if neither conclusion I nor conclusion II follows.
• E. if both conclusion I and conclusion II follow.

Answer 1

Answer: (E)

if both conclusion I and conclusion II follow.

From statement 3 and 1, we infer that any plastic can be a note and none of the notes is a coin. Therefore, none of the plastic is a coin and hence, no coin is plastic.

$\Rightarrow$ Conclusion 1 is $True$

The $2^{nd}$ statement states $some$ coins are metals. This means that some "non coins " are also metals and hence, all the plastics being metals is a possibility.

$\Rightarrow$ Conclusion 2 is $True$
