Question
Statements: Some digit are vowel. No vowel
is letter. All letter are word. Conclusions: I. Some vowel are word. II. Some digit are word. III. Some word are letter. In the question below there are four statements followed by three conclusions I, II and III. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the four statements disregarding commonly known facts.Solution
No vowel is letter (E) + All letter are word (A) → Some word are not vowel (O*). Hence conclusion I does not follow. Some digit are vowel (I) + No vowel is letter (E) → Some digit are not letter (O) + All letter are word → No conclusion. Hence conclusion II does not follow. All letter are word (A) → Conversion → Some word are letter (I). Hence conclusion III follows.
