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 ? Correct Answer Neither Conclusion 1 nor 2 nor 3 nor 4 The least possible logical Venn diagram according to given statements is, Important Points If you analyze conclusions you get conclusion 2 is complementary pair with any other conclusion, so if we have the option either conclusion 2 and conclusion 1 follows or either conclusion 2 and conclusion 3 follows or either conclusion 2 and conclusion 4 follows, that will be answered. Shortcut Trick In these types of questions, we need to eliminate conclusions. If the conclusion has 'may' or 'possible' or 'possibility' types of words, then you need to take only one possible Venn diagram which makes that conclusion true. Else you need to take only one possible Venn diagram which makes that conclusion false.
