Eight friends A, B, C, D, E, F, G and H are sitting in a circle facing the centre. B is sitting between G and D. H is third to the left of B and second to the right of A. C is sitting between A and G and B and E are not sitting opposite to each other. Who is third to the left of D ?
Answer: C
B is between G and D i.e. the order is G B D. H is third to the left of B and second to the right of A.
So, forming a circle we have :
C is between A and G. But E is not opposite B.
So, Cis between A and H.
Thus, the final arrangement becomes :
F is third to the left of D.

In an examination, Raj got more marks than Mukesh but not as many as Priya.
Priya get more marks than Gaurav and Kavita.
Gaurav got less marks than Mukesh but his marks are not the lowest in the group. Who is second in the descending order of marks ?
Answer: C
In terms of marks obtained,
Mukesh < Raj, Raj < Priya, Gaurav < Priya, Kavita < Priya, Gaurav < Mukesh.
Since Gaurav's marks are not the lowest, so Kavita's marks are the lowest.
So, the sequence becomes :
Kavita < Gaurav < Mukesh < Raj < Priya.
Clearly, in the descending order, Raj comes second.

One compulsory subject of F is Mathematic. F has Physics as one of the subjects. So, Physics is optional of F. F has Mathematics as optional and Physics as one subject.
So, Physics is the compulsory subject of E. A and D have the same subjects -- History and English. D has History as optional subject and so English is the compulsory subject of D. Subjects of A and D are reverse in regard of optional and compulsory.
So, A has History as compulsory subject and English as optional.
Chemistry is the optional subject of only one teacher. So, it is the optional of B, which only remains.
We know that History is the compulsory subject of three teachers. So, it is compulsory for A, B and C.
D is the teacher having English as her compulsory subject.
So, D is the only female teacher.
Clearly, E has the same subject combination as that of F.

(i) There is a group of five girls.
(ii) Kamini is second in height but younger than Rupa.
(iii) Pooja is taller than Monika but younger in age.
(iv) Rupa and Monika are of the same age but Rupa is tallest between them.
(v) Neelam is taller than Pooja and elder Rupa.
If they are arranged in the descending order of their ages, who will be in fourth position ?
Answer: E
We first find the sequence of height :
By (iii), we have : M < P.
By (v), we have : P < N.
Now, Rupa is tallest and Kamini is is second in height.
So, the sequence of heights is : M < P < N < K < R.
Now, we determine the age sequence :
By (ii), we have : K < R.
By (iii), we have : P < M.
By (iv), we have : R = M.
By (v), we have : R < N.
So, the sequence of ages is : N < R = M < K < P or N < R = M < P < K.
Clearly, in the desceasing order of ages, Neelam will be in fourth position (because Monika and Rupa both lie at third position).
Hence, the answer is (e).
