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
5) If both conclusions I and II follow

Some rats are chairs.
Some chairs are desks.
Conclusions:
I) Some desks are not tables.
II) All desks are tables

Directions (Q. No. 6 – 10): Each of the questions below consists of a question and two statements marked I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and

1) If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
2) If the data in statements I alone are not sufficient to answer the question, while the data in statement II alone are sufficient to answer the question.
3) If the data either in statement I or in statement II alone are sufficient to answer the question.
4) If the data even in both the statements I and II together are not sufficient to answer the question.
5) If the data in both statements I and II together are needed to answer the question

I) P and Q are the only daughters of B.
II) D is brother of P and son of A.

8. Among P, Q, R, S and T sitting in a straight line facing north, who sits exactly in the middle of the line?
I) P sits third to the left of S. T is second to the left of R and an immediate neighbour of S.
II) P is second to the left of T who is second to the left of R.

9. Who amongst P, Q, R, S, T and U is the tallest?
I) P is taller that S and T but shorter than R. Q is taller than R.
