In the question below are given two statements followed by two conclusions numbered I and II. 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: I. Some Mobile are Tablet II. Only a few Computer is Tablet Conclusions: I. Some Computer are Mobile II. Some Tablet is not Computer
In the question below are given two statements followed by two conclusions numbered I and II. 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: I. Some Mobile are Tablet II. Only a few Computer is Tablet Conclusions: I. Some Computer are Mobile II. Some Tablet is not Computer Correct Answer None of the conclusions follows
The least possible Venn diagram for the given statements is as follows,
I. Some Computer are Mobile → False (as no direct relation between computer and mobile, it is possible but not definite. so, it is false)
II. Some Tablet is not Computer → False (as some Tablet is Computer, remaining part of the Computer and Tablets has no direct relation. it is possible. but not definite. so, it is false)
Hence, None of the conclusions follows.
Note: Some + some not is not a complementary pair
Important Points
Conditions of Either-or case:
1. The elements should be the same in both the statements.
2. Both the conclusions should be false individually.
3. One conclusion should be positive and one conclusion should be negative (Complementary pair)
The two complementary pairs are:
1) All + Some not
2) No + Some
Note: Some + Some not and All+ No are not considered under Either -or case.
