Directions (Q. 1-5): 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
1) if only conclusion I follows.
2) if only conclusion II follows.
3) if either conclusion I or II follows.
4) if neither conclusion I nor II follows.

Directions (Q. 6-10): Study the following information carefully and answer the given questions:
Ten persons are sitting in two parallel rows containing 5 persons each in such a way that there is an equal distance between adjacent persons. In the 1st row E, F, G, H and I are sitting and all of them are facing south. In the 2nd row T, U, V, W and Z are sitting, but not necessarily in the same order. In the given seating arrangement each member sitting in a row faces another member of the other row.
The one who is an immediate neighbour of H is facing W. F does not sit at the extreme ends of the row. V and Z are immediate neighbours. Only one person sits between I and G. Z sits second to the left of the person who faces I. E faces the person who is on the immediate left of Z. T sits at the left end of the row. E and H are not immediate neighbours.
6. Who among the following sits between G and I?
1) H 2) F 3) E
4) T 5) None of these
7. Who among the following faces G?
1) U 2) V 3) H
4) Z 5) None of these
8. Who among the following sits second to the right of the person who faces U?
1) F 2) I 3) W
4) V 5) None of these
9. How many persons sit between E and H?
1) One 2) Two 3) Three
4) Can’t be determined 5) None of these
10. Four of the following five are alike in a certain way based on the given seating arrangement and hence form a group. Which is the one that does not belong to that group?
1) GZ 2) FV 3) WI
4) UH 5) EV
Answer :-
1. (1); No keyboard is a key (E) + All keys are rings (A) = E + A = O* = Some rings are not keyboards.
Hence, conclusion I follows.
Again, Some mice are keyboards (I) + No keyboard is a key (I) = I + E = O = Some mice are not keys. Thus, the possibility in II does not exist. Hence, conclusion II does not follow.
2. (4); I + E = O = Some mice are not keys + All keys are rings (A) = O + A = No conclusion.
Hence, conclusion I does not follow.
T here is a negative statement. Therefore, the possibility may not exist. Hence, conclusion II does not follow.
3 . (1) ; There is no negative statement. Hence, conclusion I follows.
Again, All bags are books (A) + Some books are boxes (I) = A + I = No conclusion. Hence, conclusion II does not follow.
4. (5); No kite is an aeroplane (E) + Some aeroplanes are birds (I) = E + I = O* = Some birds a re not kites.
Hence, conclusion I follows.
Again, No kite is an aeroplane => conversion => No aeroplane is a kite. Hence, conclusion II follows.
5. (2); Some pots are belts (I) + No belt is a shirt (E) = I + E = O = Some pots are not shirts. Hence, conclusion I does not follow. Again, No belt is a shirt => conversion => No shirt is a belt. Hence, conclusion II follows.
