Directions: Read the following information carefully and answer the question that follows.

In a village of Bastar district in Madhya Pradesh, only two types of people live who belong to a tribal class. The first type is known as class A, while the other is known as class B. In that village, there is no other type of person except these two. The activities of both types of people are governed by perfectly patterned norms of social behaviour. Each person of the tribe has to obey the norms. They are rigid about this.

As far as marriage is concerned, the following norms are to be followed:
(A) The people of class A cannot marry any other member of their own class, though they can marry members of class B.
(B) After being married, each male member ceases to be member of that class in which he was born, but automatically he becomes the member of the other class to which his wife belongs.
(C) As far as females are concerned, they remain the members of their own class after being married.
(D) On its birth, the child automatically becomes the member of its mother's class.

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 18

The boy born in class B will marry a girl of class A. So, the daughter will belong to class A. Thus, (1) is false.
Since the boy's daughter will belong to class A, she would marry a boy of class B and so the son-in-law would be from class B. So, (2) is false.
The boy, born in class B, will have mother born in class B and father born in class A. So, his uncle (i.e. mother's brother or father's brother) can be from class A or B.
So, (3) is true.
The boy in class B gets married to a girl in class A and himself becomes of class A.
Their son also belongs to class A, who will marry a girl of class B and himself becomes of class B.
When the son divorces, he reverts to his original class, i.e. A; hence, (4) is false.

In a village of Bastar district in Madhya Pradesh, only two types of people live who belong to a tribal class. The first type is known as class A, while the other is known as class B. In that village, there is no other type of person except these two. The activities of both types of people are governed by perfectly patterned norms of social behaviour. Each person of the tribe has to obey the norms. They are rigid about this.

Any female of class B can have
(P) grandfather (father's father) born in class B
(Q) grandmother (father's mother) born in class B

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 19

The mother of class B female belongs to class B. So, her father was born in class A. Thus, her father's mother belonged to class A, and father's father was born in class B. So, the grandfather belongs to class B and grandmother belongs to class A.

Indian Navy Tradesman Mate Mock Test - 10 - Question 20

Directions: Study the information given below and answer the question that follows.

A is the father of two children, B and D, who are of different sexes.
C is B's spouse.

The only restriction on marriage is that marriage to a sibling, to a direct descendant, or to more than one person at the same time is forbidden.

Q. According to the rules, D can marry

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 20


We can draw the above diagram based on the information given in the question. If the gender of the person is known, it is denoted by the suffix m or f. If it is not known, then it is denoted by x or y. We know, for example, that G is of the same sex as C, so we can label both as x; B and therefore, F are of the opposite sex from C, so we can label both y, and so on. Horizontal lines indicate marriage, vertical or diagonal lines indicate children. 
D is an x, and can therefore, marry any unmarried y. So, he can marry F, J, or K. 
Hence, answer option (1) is correct.

II. B > D

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 21

Given statements: A > B, B > C, C = D, D < E

On combining: A > B > C = D < E

Conclusions:

I. B = D → False (as B > C = D → B > D thus clear relation between B and D)

II. B > D→ True (as B > C = D → B > D)

Therefore, only conclusion II is True.

Indian Navy Tradesman Mate Mock Test - 10 - Question 22

In the following question assuming the given statements to be true, find which of the conclusion among given conclusions is/are definitely true and then give your answer accordingly.

Statements: 
L > F = S < T ≤ Q < P

Conclusions:

I. F < Q

II. L > S

III. T < P

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 22

Given statements: L > F = S < T ≤ Q < P

I. F < Q → True (as F = S < T ≤ Q)

II. L > S → True (as L > F = S)

III. T < P → True (as T ≤ Q < P)

Hence, all of the given conclusions follow.

Indian Navy Tradesman Mate Mock Test - 10 - Question 23

In the following question assuming the given statements to be True, find which of the conclusion among given conclusions is/are definitely true and then give your answers accordingly.

Statement:

Conclusions:

I. L < N

II. P > M

III. S = L 

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 23

Given statement: P > S ≥ M = L < J = N

I. L < N → True (as L < J = N)

II. P > M → True (as P > S ≥ M)

III. S = L → False (as S ≥ M = L gives either S = L or S > L)

Hence, both conclusions I and II are true.

Indian Navy Tradesman Mate Mock Test - 10 - Question 24

In the following question, assuming the given statements to be true, find which of the following among the given conclusions is/are definitely true and then give your answers accordingly.

Conclusion:

I. K < Y

II. L > Y

III. L = Y

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 24

Statement: S = U > K > L ≥ Y < R ≤ B

Conclusion:

I. K < Y → False (As, S = U > K > L ≥ Y)

II. L > Y → False (As, S = U > K > L ≥ Y)

III. L = Y → False (As, S = U > K > L ≥ Y)

But conclusion II and III forms a complementary pair.

Hence, either conclusion II or III follows.

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 25

Indian Navy Tradesman Mate Mock Test - 10 - Question 26

In a company, the salary of a person is directly proportional to his experience. The salary of a fresher is Rs. 20,000 per month and the salary of a person who has an experience of 2 years is Rs. 50,000.

If the company follows the methodology, what will be the salary of a person who has an experience of 5 years?

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 26

Let salary = 20,000 + k (experience)
If experience = 2 years
Salary = 50,000
50,000 = 20,000 + k(2)
 k = 15,000
So, for 5 years of experience, salary will be:
20,000 + 15,000(5)
= 95,000

Indian Navy Tradesman Mate Mock Test - 10 - Question 27

The number of fruits purchased by Ms. Paul is given by the following two equations, where a, b and c are the number of apples, bananas and oranges, respectively:

3a - 4b + 2c = 0
4a - 2b - c = 0

Which of the following represents the ratio of the numbers of apples, bananas and oranges purchased by Ms. Paul?

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 27

3a - 4b + 2c = 0 ... (1)
4a - 2b - c = 0 ... (2)
From equation (2),
c = 4a - 2b
Substituting the value of c = 4a - 2b in (1), we get
3a - 4b + 8a - 4b = 0
Or 11a = 8b
Further, c = 4a - 2b
Multiplying by 4 on both sides, we get
4c = 16a - 8b
Substituting 8b = 11a, we get
4c = 16a - 11a = 5a
Or a : b : c = a : 11a/8 : 5a/4 = 8 : 11 : 1or 16 : 22 : 20
So, option 1 is the answer.

Indian Navy Tradesman Mate Mock Test - 10 - Question 28

In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ?

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 28

Suppose the man works overtime for x hours.

Now, working hours in 4 weeks = (5 x 8 x 4) = 160.

∴ 160 x 2.40 + x x 3.20 = 432

⇒ 3.20x = 432 - 384 = 48

⇒ x = 15.

Hence, total hours of work = (160 + 15) = 175.

Free notebooks were distributed equally among children of a class. The number of notebooks each child got was one-eighth of the number of children. Had the number of children been half, each child would have got 16 notebooks. Total how many notebooks were distributed ?

Detailed Solution for Indian Navy Tradesman Mate Mock Test - 10 - Question 29

Let total number of children be x.

 Then, x x(1/8)x = (x/2)x 16   ⇔  x = 64

 Number of notebooks =(1/8)x2 =(1/8x 64 x 64)= 512
