In the questions given below, there are four statements followed by four conclusions I, II, III and
IV. You have to take the four given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. If 'L & M' means 'All L is M', 'L @ M' means 'Only L is M', 'L # M' means 'No L is M', 'L > M' means 'Only a few L is M'. 'L < M' means 'Some L is M'. 'L ? M' means 'Some L is not M'. 'L + M' means 'All L is M is a possibility'. Statements: Word & Alphabet; Alphabet & Number; Alphabet > Digit; Digit < Numeral Conclusion:
I. Number ? Digit
II. Alphabet < Numeral
III. Numeral + Word
IV. Digit ? Numbe

After decoding the codes, we get, Statements: Word & Alphabet means All Word is Alphabet Alphabet & Number means All Alphabet is Number Alphabet > Digit means Only a few Alphabet is Digit Digit < Numeral means Some Digit is Numeral Conclusion: I. Number ? Digit means Some Number is not Digit. II. Alphabet < Numeral means Some Alphabet is Numeral III. Numeral + Word means All Numeral is Word is a possibility. IV. Digit ? Number means Some Digit is not Number. All Alphabet is Number (A) → Conversion → Some Number is Alphabet (I) + Only a few Alphabet is Digit (I) → Some Number is not Digit (O). Hence conclusion I follows but conclusion IV does not follow. Only a few Alphabet is Digit (I) + Some Digit is Numeral (I) → No conclusion. Hence conclusion II does not follow. All Word is Alphabet (A) + Only a few Alphabet is Digit (I) → Probable conclusion → Some Word is Digit (I) + Some Digit is Numeral (I) → Probable conclusion →  All Numeral mam be Word (A). Hence conclusion III follows.
