In Gargi’s family there are 7 members A, B, C, D, E, F and G other than her consisting of Mother, Father, Brother, Sister, Uncle, Grandfather and Grandmother. They are Doctor, Professor, Director, Actor, Minister, Business Person and Artist by profession not necessarily in the same order. Gargi is a Manager of a leading restaurant and invites the family to her restaurant having round tables for seating to have dinner. The family members select a table for dinner while Gargi is on duty.
Few other details are :
(a) The mother and father do not sit together.
(b) C is seated on the immediate left of Professor and A sits with B.
(c) The artist is either the sister or grandmother and sits to the immediate right of Father.
(d) The grandmother is seated on the immediate left of D who is an actor.
(e) G who is an artist sits with the Business person, F who is a female.
(f) E sits one place away to the left of Director.
(g) There is one family member between Grandmother and C who is a Director.
(h) Father is a doctor and sits between Professor and Sister.
(i) Brother is not a Professor and sits with Grandmother.
If C is the Uncle, then Professor is :
- (a)
Grandfather
- (b)
A
- (c)
B
- (d)
Mother
Answer: Option A
Text Explanation :
The seat numbers on the dining table can be defined as below:
From b - if C is seated on seat no.5, then the one who is a professor is on the seat no. 6.
From f, g and d - C is a Director and E sits second to the left of C. Also, there is one person between C and Grandmother of Gargi. Therefore, Grandmother can be at seat no. 3 i.e. E or at seat no. 7.
The Grandmother is seated to the immediate left of D who is a actor. So, there are two cases possible here:
If Grand mother is at seat no. 3, then D is at seat no. 4(CASE I ) and
If the Grandmother is at seat no. 7, the D is at seat no. 1(CASE II)
From h - Father, who is a doctor is between Professor and Sister of Gargi.
In Case II where Grandmother is at seat no. 7, the two neighbours of Professor are C(Director) and Grandmother. So in this case Father(Doctor) can't be between professor and a sister. So Case II gets eliminated.
Therefore, Grandmother is at seat no. 3 i.e. E is a Grandmother and D is at seat no. 4. Also, Father is at seat no. 7 and sister of Gargi is at seat no. 1.
From c and g - G, an artist is a sister of Gargi and is at seat no. 1. F, who is a Business person is at seat no. 2. As there are on three females in Gargi's family i.e. Mother, Sister and Grandmother and as G is a sister and E is a Grandmother of Gargi, therefore F is a Mother of Gargi.
So D is an actor is a Brother of Gargi.
Therefore the arrangement will be:
Seat no. 1 - G/Artist/Sister
Seat no. 2 - F/Business Person/Mother
Seat no. 3 - E/Minister/Grand Mother
Seat no. 4 - D/Actor/Brother
Seat no. 5 - C/Director/Grandfather or Uncle
Seat no. 6 - A or B/Professor/Grandfather or Uncle
Seat no. 7 - A or B/ Doctor/ Father
Therefore,if C is a Uncle, then Professor is a Grandfather.

Read the following information to answer the question that follows.
In one of the islands of Neverland, people from two tribes exist namely A and B. On the island there is no other tribe except these two. The activities of these tribes are governed by rigid norms and are strictly obeyed for marriages. The norms are:
- The people of one tribe cannot marry any other member of their own tribe though they can marry people from other tribe.
- After being married, each male member ceases to be a member of that tribe in which he was born and becomes the member of the tribe to which his wife belongs.
- The females continue to remain members of the tribe in which they were born even after marriage.
- On birth, the child becomes the member of the mother’s tribe.
- The males become members of the tribe in which they were born when they become divorcee or widower.
- As per norms, nobody can have more than one spouse at a given point of time.
A female in tribe B can have
a. Maternal Grandmother born in tribe A
b. Paternal Grandmother born in tribe A
- (a)
Only a can be true
- (b)
Only b can be true
- (c)
Both a and b are true
- (d)
Neither a nor b can be true
Answer: Option B
Text Explanation :
A female always remains in the same tribe, irrespective of whether she is married, unmarried, divorced or widowed.
Maternal grandmother is the mother’s mother. If the female is in tribe B, her mother as well as maternal grandmother will always be in tribe B.
Hence, a female in tribe B cannot have her maternal grandmother in tribe A.
Hence, statement a cannot be true.
Now, consider a lady (X) born in tribe A. When she marries, she remains in tribe A, and her husband enters tribe A from tribe B. Assume that she has a son (Y).
Y will also be in tribe A.
When Y marries, Y will move to tribe B. Assume that Y has a daughter (Z). Z will be in tribe B, as it is her mother’s tribe.
Thus, a female in tribe B (i.e. Z) can have her paternal grandmother (i.e. X) born in tribe A.
Hence, statement b is true.
Hence, option (b).
Workspace:
A boy born in tribe B
- (a)
Can have his daughter in tribe B
- (b)
Can have his daughter in law in tribe A
- (c)
Can have uncle from any tribe
- (d)
Can have a divorced son in tribe B
Answer: Option C
Text Explanation :
A boy born in tribe B (say X), can have a son, daughter, son-in-law or daughter-in-law only if he is married. When he marries, he moves to tribe A. Also, his daughter always remains in tribe A (as it is her mother’s tribe).
Hence, a boy born in tribe B cannot have his daughter in tribe B.
Hence, option (a) is eliminated.
The son of X will be in tribe A (till marriage). When he marries, this son and daughter-in-law will be in tribe B. Hence, X cannot have his daughter-in-law in tribe A.
Hence, option (b) is eliminated.
If this married son gets divorced, he moves back to his mother’s tribe i.e. tribe A. Hence, X cannot have a divorced son in tribe B.
Hence, option (d) is eliminated.
Hence, option (c).
Note:
You need not check option 3. However, it can be verified as under:
If the boy is born in tribe B, his mother and her brother will also be in tribe B. This uncle will remain in tribe B before marriage and move to tribe A after marriage.
Hence, a boy born in tribe B can have an uncle in any tribe.
Workspace:
Which of the following marriages are not permissible as per norms
- (a)
Any widower marries his wife’s sister
- (b)
Any widow marries the former divorced husband of her daughter
- (c)
Any girl of the tribe B marries her mother’s brother
- (d)
Any widower born in tribe A marries his brother’s widow
Answer: Option C
Text Explanation :
Since an invalid marriage is to be found, marriages will be possible in three out of four options.
Considering each option.
Option 1:
Let X be born in tribe A. When he marries, he moves to tribe B. He moves back to tribe A, on being widowed. Meanwhile, his wife’s sister is still in tribe B. Since he is currently unmarried, it is possible for him to
marry his wife’s sister.
Option 2:
A lady and her daughter will be always remain in the same tribe (say A). Her daughter’s husband would originally have been from tribe B, and would have entered tribe A after marriage. He would have gone back to
tribe B after divorce.
Since the female (widowed) and male (divorced) are currently unmarried and in different tribes, they can get married.
Option 3:
If the girl is in tribe B, her mother as well as mother’s brother are also in tribe B.
Since two people of the same tribe cannot marry, this marriage is not permissible.
Also, this uncle will be in tribe A only if he is married. The marriage is still not permissible as a person can only have one spouse at a time.
Hence, option (c).
Note:
You need not check option 4, but it can be verified that this marriage is possible.

From the question W is the niece of X, So W is a female.
In option A, We see that all X , Y , Z and W are brothers and sisters.
In option B, W is father of Y. So, W is a male.
Consider option C.
It says X is Y's brother, Y is W's father and W is Z's sister.
Hence W is X's niece.
Hence, option (c).

Read the following information to answer the question that follows.
P – Q means Q is father of P
P × Q means Q is brother of P
P ÷ Q means Q is wife of P
P + Q means Q is sister of P
Which of the following means M is the grandfather of T?
- (a)
T – C ÷ L + N × M
- (b)
T – R ÷ Z + L × M
- (c)
T ÷ Z × L + F – M
- (d)
None of these
Answer: Option D
Text Explanation :
Option 1:
M is the brother of N, who is the sister of L So, M is also the brother of L. L is the wife of C who is the father of T. Thus, M cannot be the grandfather of T.
Option 2:
M and T are at the same position in option 2 as in 1. Also, since the symbols and their position in option 2 is the same as that in option 1, the relation between the two is also the same.
Option 3:
M is the father of F who is the sister of L. L is the brother of Z. Thus, M is the father of F, L and Z. Z is the wife of T. Thus M cannot be the grandfather of T.
Thus, none of the given options means M is the grandfather of T.
Hence, option (d).
Alternatively,
Except for the ‘−’ sign, all the other signs convey a relationship in the same generation. For M to be the grandfather of T, there should be two ‘−’ signs. This is not present in any of the options.
Hence, option (d).
