| Direction: In each question below are given two/three 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. Give answer |
| Statements: All blue are brown. |
| All black are bags. |
| Some brown are not bags. |
| Conclusions: |
| I. Some brown are not black. |
| II. No blue is a bag, |
A) if only conclusion I follows.
B) if only conclusion II follows.
C) if either conclusion I or II follows.
D) if neither conclusion I nor II follows.
E) if both conclusions I and II follow.
Correct Answer: A
Solution :
Suppose 'Some brown are not black' is not true. It means All brown are black. Now, All brown are black +A11 black are bags = A +A= A=A11 brown are bags. But this can't be true because 'Some brown are not bags' (given). Hence, our assumption is wrong and conclusion I is true. All blue are brown + Some brown are not bags = A + O = No conclusion. Hence, II does not follow.
