Question
Statements : Some tablets are vowels. No vowel
is a letter. All letters are words. Conclusions:I. Some tablets are not letters. II. All words are vowels. III. All tablets are words. In each of the questions below are given three statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions definitely does not follow logically from the given statements disregarding commonly known facts.Solution
Some tablets are vowels(I) + No vowel is a letter(E) ⇒ Some tablets are not letters(O). Hence conclusion I follows. No vowel is a letter(E) + All letters are words(A) ⇒ Some words are not vowels(O*). Hence conclusion II does not follow. Some tablets are vowels(I) + No vowel is a letter(E) ⇒ Some tablets are not letters(O) + All letters are words (A) ⇒ No conclusion. Hence conclusion III does not follow. ALTERNATE SOLUTION: Minimal possibility:
