2) Only 3 people sit between D and E.
3) D is not an immediate neighbour of I or J
and sits second to the left of K.
4) F sits second to the right of G only 3
people sit between F and J.
5) Only 1 person sits between J and I (either
from left or right).
(Now the only leftover person is H and will sit
in the only left place)
The above arrangement will be the final
arrangement.
F, J, G, I ? Group of people sitting at the
corners.
K ? sits at the middle of the side.
Hence, K does not belong to the group.
10. Ans. D.
People: D, E, F, G, H, I, J and K.
Note – 1: 4 sit at the corner facing outside
and 4 sit in the middle of the sides facing the
centre.
1) E does not sit at any of the corners of the
table.
(Therefore, E sit at the middle of the side)
2) Only 3 people sit between D and E.
3) D is not an immediate neighbour of I or J
and sits second to the left of K.
4) F sits second to the right of G only 3
people sit between F and J.
5) Only 1 person sits between J and I (either
from left or right).
(Now the only leftover person is H and will sit
in the only left place)
The above arrangement will be the final
arrangement.
When we count from the right of J, K is an
immediate neighbour of J.
Hence, none sits between J and K when
counted from the right of J.

14. Ans. A.
Given: A = B > F; B > M > O; F > S; R < S
Conclusion:
I. S < A ? True (as A > F > S)
II. F < O ? False (as B > F; B > O therefore
we can ’t find exact relationship between
them)
Hence, only conclusion I follows.
15. Ans. E.
Given: D = R > E = B; S = M = E > D; G >
B
Conclusion:
I. D > G ? False (as E = B; E > D and G > B
? G > B = E > D ? G > D)
II. B < R ? False (D = R > E and B = E > D
? B = E > D = R)
Hence, Neither I nor II follows.
16. Ans. C.
Given: E = S > F = C; T = N = F > E; H > C
Conclusion:
1) T < C ? False (as F = C; T = N = F ? T =
F = C therefore T = C)
2) C = T ? False (as F = C; T = N = F ? T =
F = C therefore T = C)
As T = C therefore either T < C or T = C.
Hence, either I or II follows.
17. Ans. B.
Given: M = L = N = Q < P < V = S; Q > G
On Combining: M = L = N = Q > G; G < P
< V = S
Conclusion:
1) G = S ? False (as G < P < V = S
therefore we can ’ t find any relationship
between G and S)
2) M > G ? True (as M = L = N = Q > G)
Hence, Only conclusion II follows.
18. Ans. D.
Given: Q > A = Z = X = C; Z = H
On combining: Q > A = Z = H; H = Z = X
= C
Conclusion:
1) Q > H ? True (asQ > A = Z = H)
2) Z = C ? True (as H = Z = X = C)
Hence, both conclusions I and II follow.
19. Ans. B.
1) There are 5 boxes between box P and box
R.
2) Box T is kept immediately above R.
3) 3 boxes are kept between box T and box
S.
4) Number of boxes between P and S is same
as the number of boxes between T and Q.
5) Box U is kept below box Q.
6) There is only one box kept between U and
V.
(Therefore Case – 1 will gets eliminated)
6) Box W is kept somewhere below X.
