Question
Statements: All Letters are Alphabets
Only few Letters are Numbers All Digits are Alphabets Conclusion: I. Some Letters are Digits. II. All Numbers can be Alphabets. In the question below there are three statements followed by two conclusions I and II. You have to take the three 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 three statements disregarding commonly known facts.Solution
All Letters are Alphabets (A) + [All Digits are Alphabets (A) β Conversion] β Some Alphabets are Digits (A) β No conclusion. Hence conclusion I does not follow. All Letters are Alphabets (A) β Some Alphabets are Letters (I) + Only few Letters are Numbers (I) β Probable conclusion β All Numbers can be Alphabets (A). Hence conclusion II follows.
