Consider two Statements and four Conclusions given below. You have to take the Statements to be true even if they seem to be at variance from the commonly known facts. Read all Conclusions and then decide which of the given Conclusion(s) logically follows/follow from the Statements, disregarding the commonly known facts.
Statement-1: Some greens are blues.
Statement-2: Some blues are blacks.
Conclusion-1: Some greens are blacks.
Conclusion-2: No green is black.
Conclusion-3: All greens are blacks.
Conclusion-4: All blacks are greens.
Which one of the following is correct?
Conclusion-1 and Conclusion-2 only
Conclusion-2 and Conclusion-3 only
Conclusion-3 and Conclusion-4 only
Neither Conclusion 1 nor 2 nor 3 nor 4
Solution
From 'Some greens are blues' and 'Some blues are blacks', no definite link is established between greens and blacks. 'Some greens are blacks', 'No green is black', 'All greens are blacks' and 'All blacks are greens' are all merely possibilities, none of which definitely follows. Hence none of the conclusions follows.
