(d) either (1) or (4) (e) None
Solution :
We first find the sequence of heights
by (3) we have :M < P
by (5) we have : P < N
Now, Rupa is tallest and kamini is second in height.
So the sequence of heights is : M < P < N < K < R.
Now, we determine the age sequence
by (2) we have : K < R.
by (3) we have : P < M.
by (4) we have : R = M.
by (5) we have : R < N.
So the sequence of ages is:N < R = M < K < P or N < R = M < P < K.
Answer for 6th question is (e),in the increasing order of heights,
Neelam is in third position.
Answer for 7th question is (e), in the descending order of ages,
Neelam will be in fourth position (because Monika and Rupa both

age is x/2. C is twice the age of D i,e D is half the age of C i,e
D's
age is x/4. So, the descending order of ages is F, B, A, C, D.
Clearly, F is the oldest and is the youngest.
Directions (questions 7 to 11) Read the following information and
answer
the questions given below it:
(1)Seven students P, Q, R, S, T, U and v take a series of tests.
(2)No two students get similar marks.
(3)V always scores more than P.
(4)P always scores more than Q.
(5)Each time either R scores the highest and t gets the least or
alternatively S scores the highest and U or Q scores the least.
7.If S is ranked sixth and Q is ranked fifth, which of the following
can be true?
(a) V is ranked first or fourth (b) R is ranked second or
third
(c)Pis ranked second or fifth (d) U is ranked third or
fourth
(e) T is ranked fourth or fifth.
8.If R gets more, V should be ranked not lower than:
(a) second (b) third (c) fourth
(d) fifth (e) sixth
9.If R is ranked second and Q is ranked fifth, which of the following
must
be true?
(a) S is ranked third (b) T is ranked sixth
(c) P is ranked sixth (d)V is ranked fourth
(e) U is ranked sixth
10.If S is ranked second, which of the following can be true?
(a) U gets more than V (b) V gets more than S
(c) P gets more than R (d)P gets more than V
(e) T gets more than Q
11.If V is ranked fifth, which of the following must be true?
(a) S scores the highest (b)R is ranked second
(c) T is ranked third (d)Q is ranked fourth
(e) U scores the least
Solution for 7th to 11th :
In terms of scores we have :
V > P, P > Q i,e V > P > Q.
If R scores the highest, we have R > ---------- > T.
If S scores the highest, we have S > ----------- > Q
or S > ---------- > U.
Answer for 7th question is (d), If S is ranked sixth and Q is ranked
fifth,we have
_ > _ > _ > _ > Q > S > _
In this case, R will ran the highest and thus T will rank the least.
we have
R > _ > _ > _ > Q > S > T
Also, the order V > P > Q will be maintained i,e V and P will have
second,
third or
fourth places. So, statements (a), (b), (c), (e) cannot follow.
Thus (d) is the answer.
Answer for 8th question is (c), Again, if R ranks most, T ranks
lowest
and occupies seventh place. Since V always ranks above P and Q so in
the maximum, P and Q will occupy fifth and sixth places. Thus, V will
not rank lower than fourth.
Answer for 9th question is (b), If R is ranked second, S will rank
first
and Q and U lowest. But Q ranks fifth. So, U ranks lowest. Also, the
order
V > P > Q will be followed.
So, the arrangement will be S > R > V > P > Q > _ U.Thus , the sixth
place
will be occupied by T.
Answer for 10th question is (a), If S ranks second, R ranks first and
T
ranks lowest.The order V > P > Q will be followed.
So, the arrangement
will be R > S > _ > _ > _ > _ > T.
Clearly, statements (b), (c), (d) and (e) cannot follow. so the
answer is
(a).
Answer for 11th question is (a), If V ranks fifth, P and Q coming
before it
will occupy sixth and seventh places respectively i,e Q ranks least.
So,
S will score the highest.

older and also taller, who among them should be chosen?
(a) A (b) B (c) C (d) D
e) E
Solutions for 12th to 16th :
In terms of age we have:
E < B, C < A, A < E, A < D
So, we have C < A< E < B, A < D.
In terms of height we have
B < C, D < C, E < C, D < A.
Answer for 12th question is (e) : Either B or D is the eldest.
Answer for 13th question is (e) : It cannot be determined for sure.
Answer for 14th question is (a) : B is shorter than C, so B is
not the tallest.
Thus (1) is correct. B and E are shorter than C. So, it cannot be
concluded that B is shorter to E. Thus (2) is incorrect.
A single definite order of heights cannot be
obtained from the
given information. So (3) is incorrect.
Answer for 15th question is (e) :Since no definite order of height
can be obtained.So it cannot be determined for sure how many persons
lie between F and E.
Answer for 16th question is (b) :A and C are youngest so they cannot
be selected.
D is shorter than two persons A and C.
B is shorter than C only and is only relatively order. So, B will be
selected.
E is younger than B.

(d) None of these
Solution for 17th to 20th :
Answer fro 17th question is (a) : Sachin*Madan-Reena means Sachin
and Madan are of the same age and Reena is younger than Madan.
This means that Reena is the youngest.
Answer for 18th question is (b) : X+Y+Z means X is younger than Y
and Y is younger than Z. This can also be written as Z-Y-X.
Answer for 19th question is (a) : Farha-Fardina-Arif means Fardina
is younger than Farha and Arif is younger than Fardina. This means
that Arif is younger than Farha.
So, Arif cannot be the father
of Farha.
Answer for 20th question is (d) : Deven-Shashi*Hemant means Shashi
is younger than Deven ans Shashi and Hemant are of the same age.
Thus Deven is the oldest.
Now, the opposite statements would mean : Deven is the youngest.
(1)Hemant+Shashi+Deven means Hemant is younger than Shashi, who is
younger than Deven.So, Deven is the oldest.
(2)Hemant-Shashi+Deven means Shashi is younger than both Hemant
and Deven.Thus eother Hemant or Deven is the oldest, but Deven
is not the youngest.
(3)Shashi*Hemant+Deven means Shashi and Hemant are of the same age
and Hemant is younger than Deven. So, Deven is the oldest.

Solution : We first find the sequence of heights
by (3) we have :M < P
by (5) we have : P < N
Now, Rupa is tallest and kamini is second in height.
So the sequence of heights is : M < P < N < K < R.
Now, we determine the age sequence
by (2) we have : K < R.
by (3) we have : P < M.
by (4) we have : R = M.
by (5) we have : R < N.
So the sequence of ages is : N < R = M < K < P or N < R = M < P <
K.
Answer for 6th question is (e), in the increasing order of heights,
Neelam is in third position.
Answer for 7th question is (e), in the descending order of ages,

EXERCISE
1.Compare the knowledge of persons X, Y, Z, A, B and C in relation
to each other.
1.X knows more than A.
2.Y knows as much as B.
3.Z knows less than C.
4.A nows more than Y.
The best knowledge person amongst all is:
(a) X (b) Y (c) A (d) C
Answer is (a), Clearly, we have : A < X, Y = B, Z < C, Z < B, Y < A
thus the sequence becomes X > A >Y = B > C > Z.
So, X is the best knowledgeable person.
2.Five children were administrated psychological tests to know their
intellectual levels. In the report, psychologists pointed out
that the child A is less

child A is more
intelligent than child E. Which child is most intelligent?
(a) A (b) B (c) D (d) E (e) None of these
Answer is (c), we have A < B, C < D, B < C and E < A.
So, the sequence becomes: E < A < B < C < D.
Clearly, child D is most intelligent.
3.In an examination, Raj got more marks than Mukesh but not as many
as Priya.
Priya got more marks than Dinesh and Kamal. Dinesh got less marks
than Mukesh
but his marks are not the lowest in the group. Who is the second
in the descending
order of marks?
(a) Priya (b) Kamal (c) Raj (d) Cannot be determine
(e) None of these
Answer is (c)
In terms of marks obtained
Mukesh < Raj, Raj < Priya, Dinesh < Priya, Kamal < Priya, Dinesh <
Mukesh.
Since Dinesh mars are not the lowest, so Kamal's marks are the
lowest.
So, the sequence becomes: Kamal < Dinesh < Mukesh < Raj < Priya.
Clearly, in the descending order, Raj comes second.
Read the following information carefully and answer the questions
given below it:
(A)Gopal is shorter than Ashok but taller than Kunal.

Solution for 4th and 5th questions.
In terms of height we have : Gopal < Ashok, Kunal < Gopal, Navin <
Kunal,
Navin < Jayesh, Jayesh < Ashok.
So, the sequence becomes: Navin < Kunal < Gopal < Jayesh < Ashok.
Answer for 4th question is (b), Clearly, Ashok is tallest.
Answer for 5th question is (c), Clearly, statement C is not
necessary.
6.B is twice as old as A but twice younger than F.
C is half the age of A but twice the age of D.
Which two persons from the pair of oldest and youngest?
(a) F and A (b) F and D (c) B and F (d) F and C (e) None of
these
Answer is (b)
Let's A's age be x, then B's age is 2x. B is twice younger than F i,e
F is
twice older than B. So, F's age is 4x. C is half the age of A i,e C's
age is x/2. C is twice the age of D i,e D is half the age of C i,e
D's age
is x/4. So, the descending order of ages is F, B, A, C, D.
Clearly, F is the oldest and is the youngest.
Directions (questions 7 to 11) Read the following information and
answer the
questions given below it:
(1)Seven students P, Q, R, S, T, U and v take a series of tests.
(2)No two students get similar marks.
(3)V always scores more than P.
(4)P always scores more than Q.
(5)Each time either R scores the highest and t gets the least or
alternatively
S scores the highest and U or Q scores the least.
7.If S is ranked sixth and Q is ranked fifth, which of the following
can be true?
(a) V is ranked first or fourth (b) R is ranked second or third
(c)Pis ranked second or fifth (d) U is ranked third or fourth
(e) T is ranked fourth or fifth.
8.If R gets more, V should be ranked not lower than:
(a) second (b) third (c) fourth (d) fifth (e) sixth
9.If R is ranked second and Q is ranked fifth, which of the following
must be true?
(a) S is ranked third (b) T is ranked sixth (c) P is ranked
sixth
(d)V is ranked fourth (e) U is ranked sixth
10.If S is ranked second, which of the following can be true?
(a) U gets more than V (b) V gets more than S (c) P gets more than R
(d)P gets more than V (e) T gets more than Q
11.If V is ranked fifth, which of the following must be true?
(a) S scores the highest (b)R is ranked second (c) T is ranked
third
(d)Q is ranked fourth (e) U scores the least
Solution for 7th to 11th :
In terms of scores we have :
V > P, P > Q i,e V > P > Q.
If R scores the highest, we have R > ---------- > T.
If S scores the highest, we have S > ----------- > Q or S > --------
-- > U.
Answer for 7th question is (d), If S is ranked sixth and Q is ranked
fifth, we have
_ > _ > _ > _ > Q > S > _
In this case, R will ran the highest and thus T will rank the least.
we have
R > _ > _ > _ > Q > S > T
Also, the order V > P > Q will be maintained i,e V and P will have
second, third or
fourth places. So, statements (a), (b), (c), (e) cannot follow.
Thus (d) is the answer.
Answer for 8th question is (c), Again, if R ranks most, T ranks
lowest and occupies
seventh place. Since V always ranks above P and Q so in the
maximum, P and Q will
occupy fifth and sixth places. Thus, V will not rank lower than
fourth.
Answer for 9th question is (b), If R is ranked second, S will rank
first and
Q and U lowest. But Q ranks fifth. So, U ranks lowest. Also,
the order V > P > Q will be followed.
So, the arrangement will be S > R > V > P > Q > _ U. Thus , the
sixth place
will be occupied by T.
Answer for 10th question is (a), If S ranks second, R ranks first and
T ranks
lowest. The order V > P > Q will be followed. So, the arrangement
will
be R > S > _ > _ > _ > _ > T.
Clearly, statements (b), (c), (d) and (e) cannot follow. so the
answer is (a).
Answer for 11th question is (a), If V ranks fifth, P and Q coming
before it will
occupy sixth and seventh places respectively i,e Q ranks least.
So, S will score the highest.

older and
also taller, who among them should be chosen?
(a) A (b) B (c) C (d) D (e) E
Solutions for 12th to 16th :
In terms of age we have:
E < B, C < A, A < E, A < D
So, we have C < A< E < B, A < D.
In terms of height we have
B < C, D < C, E < C, D < A.
Answer for 12th question is (e) :
Either B or D is the eldest.
Answer for 13th question is (e) :
It cannot be determined for sure.
Answer for 14th question is (a) :
B is shorter than C, so B is not the tallest.
Thus (1) is correct. B and E are shorter than C. So, it cannot be
concluded that B
is shorter to E. Thus (2) is incorrect. A single definite order of
heights
cannot be obtained from the given information. So (3) is incorrect.
Answer for 15th question is (e) :
Since no definite order of height can be obtained.
So it cannot be determined for sure how many persons lie between F
and E.
Answer for 16th question is (b) :
A and C are youngest so they cannot be selected.
D is shorter than two persons A and C.
B is shorter than C only and is only relatively order. So, B will be
selected.
E is younger than B.

Solution for 17th to 20th :
Answer fro 17th question is (a) :
Sachin*Madan-Reena means Sachin and Madan are of the same age and
Reena
is younger than Madan. This means that Reena is the youngest.
Answer for 18th question is (b) : X+Y+Z means X is younger than Y and
Y
is younger than Z. This can also be written as Z-Y-X.
Answer for 19th question is (a) : Farha-Fardina-Arif means Fardina is
younger than
Farha and Arif is younger than Fardina. This means that Arif is
younger than Farha.
So, Arif cannot be the father of Farha.
Answer for 20th question is (d) : Deven-Shashi*Hemant means Shashi is
younger than
Deven ans Shashi and Hemant are of the same age. Thus Deven is the
oldest. Now, the
opposite statements would mean : Deven is the youngest.
(1)Hemant+Shashi+Deven means Hemant is younger than Shashi, who is
younger than Deven.
So, Deven is the oldest.
(2)Hemant-Shashi+Deven means Shashi is younger than both Hemant and
Deven.
Thus eother Hemant or Deven is the oldest, but Deven is not the
youngest.
(3)Shashi*Hemant+Deven means Shashi and Hemant are of the same age
and Hemant is
younger than Deven. So, Deven is the oldest.
