In the question below are given six statements followed by four conclusions numbered I, II, III and IV. 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 the given conclusions logically follows from the given statements disregarding commonly known facts. Statements: All Petrol are Gasoline. No petrol is Water. Some Water are Gas. Some Moisture are Gas. All Gasoline are Fire No Moisture is Fire Conclusions: I. Some Moisture are Gasoline. II. Some Water are Moisture. III. Some Gasoline are Gas. IV. Some Petrol are Moisture. Correct Answer None follows The Venn diagram for the given statements is as follows, [ alt="vyoma18" src="//storage.googleapis.com/tb-img/production/18/07/vyoma18.PNG" style="height:174px; width:343px"> Based on that we will check conclusions: I. Some Moisture are Gasoline → Clearly not follow, hence false. II. Some Water are Moisture → It’s possible but not definite, hence false. III. Some Gasoline are Gas → It’s possible but not definite, hence false. IV. Some Petrol are Moisture → Clearly not follow, hence false. Hence None statement follows.
