Direction (Q. 6 - 10): In each of the questions given below are given three statements followed by three conclusions numbered I, II and III. 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.
Statement: All books are students.
All students are houses.
All schools are houses.
Conclusions I. Some houses are schools.
II. Some students are books.
III. Some houses are books.
All schools are houses (A) - Conversion - Some houses are schools (1) Hence I follows. Al books are students (A) - conversion - some studetns are books (1). Hence II follows. All books are students (A) + All students are houses = A + A = A - Conversion - I. some houses are books. Hence III follows.
All snakes fare trees + some trees are roads = A + I = No Conclusions. Hence II does not follows. Some trees are roads + All roads are mountains = I + A = I = Some trees are mountains - Conversion - Some mountains are trees (I). Hence III follows.
No jungle is a bird + Some birds are rains E + I = O = Some rains are not jugnles. However I and II are a complementary pair. All tigers are jungles + No jungles is a bird = A + E = E = No tigers are birds. Hence III follows by conversion.
Some pens are swords + All swords are dogs = I + A = I = Some pens are dogs. Some pens are dogs + Some dogs are foxes = I + I = No conclusions. All swords are dogs + Some dogs are foxes. A + I = No conclusion. Hence III is invalid.
