According to the given information in the question, 'Author' is related to 'Writing.
Here, we have to find out the word to which thief is related.

Here, we can conclude that the main work of an 'Author' is 'Writing', in the same way, the main work of a 'Thief' is 'Stealing'.

Hence, the correct answer is to steal.

First Method

According to the question, Rajan's position from one end is 15th, and from the other end is 13th .

So, total no. of students in the class = ( position from one end + position from another end) - 1

Total no. of students = (15 + 13) - 1

Total no. of students = 27

Second Method

Rajan's position from one end is 15th, which means that 14 students are before him, and from other end is 13th i.e. 12 students are after him.

Total no. of students = 14 + 1(Rajan) + 12

Total no. of students = 27

Total number of students in class = 21

The position of Shyamal from the last in his class = 13^th

The position of Shyamal from the beginning = (Total students in the class - Shyamal's position from the last) + 1

= (21 - 13) + 1 = 9^th

Total number of students in Sanju's class = 40

Sanju's position from one end = 30^th

Sanju's position from the other end = (Total number of students in the class - his position from the one end ) + 1

= (40 - 30) + 1

= 11^th  

Now Nivedita becomes 18^th from the left and 23^rd from right in a row.

Total number of girls in row = (Position of Nivedita from the left side + Position of Nivedita from right in row) - 1

= (18 + 23) - 1

= 40

Position of Vimla from the right = (Total numbers of girls – Position of Vimla from the left) + 1

= (40 - 15) + 1

= 26^th

According to the question:

Now, Manorama becomes ${25}^{\text{th}}$ from the right and ${10}^{\text{th}}$ from left in the row.

Then,

Total number of ladies in row $=$ (Position of Manorama from the left side $+$ Position of Manorama from right side in row) $- 1$

$=\left(10+25\right)–1$

$=34$

Hence, $34$ is the correct answer.

Ramesh started from a fixed point O and goes 15 m towards North at point A, and then after turning to his right, he goes 15 m at point B. Then he goes 10 m at point C, 15 m at point D, and 15 m at point E after turning to his left each time.

The distance between final point E and initial point O is given by

OE = OD - DE

OE = OA + AD - DE

OE = OA + BC - DE

OE = 15 + 10 - 15 = 10 m 

So, the distance between the initial and final position of Ramesh is 10 m.

Sonalika started from the fixed point $O$, then she goes $12 km$towards North at point $B$, then she goes $8 km$ towards South at point $A$ and in the end, she goes $3 km$ towards East at point $C$.

The shortest distance between the initial point $O$ and final point $C$ is given by

$OC=\sqrt{O{A}^2+A{C}^2}$

$OC=\sqrt{{\left(OB-AB\right)}^2+A{C}^2}$

$OC=\sqrt{{\left(12-8\right)}^2+{\left(3\right)}^2}$

$OC=\sqrt{16+9}$

$OC=5 km$

So, the shortest distance between initial and final position of Sonalika is $5 km$ and clearly the final point $C$ is in North-East direction of initial point $O$ .

Sunita started from the fixed point O, then she goes 30 km towards North at point A, then she goes 15 km towards right at point B and finally she goes 30 km towards right at point C.

The shortest distance between the initial point O and final point C is given by 

OC = AB = 15 km

Also, C is in the East direction of O.

So, Sunita is finally at 15 km in East direction of initial point O.

Kanchan started from a fixed point N, then she goes 5 m towards East at point M, then she goes 35 m after turning to her left at point O. Again she goes 10 metres after turning to her right at point P. After this she goes 35 m after turning to her right at point Q.

The shortest distance between the initial point N and final point Q is given by 

NQ = NM + MQ

NQ = NM + OP

NQ = 5 + 10 = 15 m

So, the shortest distance between the initial point N and the final point Q is 15 m.

Shri Prakash started from point O, then he walked 40 metres facing towards North at point A. From there he walked 50 metres after turning to his left at point B. After this he walked 40 metres after turning to his left at point C.

The shortest distance between the initial point O and final point C is given by

OC = AB = 50 m

C is in west direction of O.

So, the final position of Shri Prakash is 50 m, west from the initial point O.

Given Statements:  
All kings are beggars.
All beggars are monks.

After analysing the given statements, the following Venn diagram can be formed.

From the above diagram, let's check each conclusion:
Conclusion I. All beggars are kings will be false as beggars in the superset.
Conclusion II. All kings are monks will be true as kings is the subset of the set monks.
Conclusion III. Some monks are beggars will be true as the monk is the superset of the set of beggars.
Conclusion IV. No monk is a beggar will be false as all the given statements are positive.
 

Hence, the correct answer is only II and III follow.

According to the given statement, the following Venn diagram can be drawn,

Now, let's check each conclusion,
Conclusion I. All benches are chairs will be false as the set of chairs is the subset of benches.

Conclusion II. All benches are boxes will be false as the set of boxes is the subset of benches.

Conclusion III. Some benches are chairs will be true as the set of benches is the superset of chairs.

Conclusion IV. Some chairs are boxes will be true as the set of chairs is the superset of boxes.

Hence, the correct answer is only III and IV. 

After brainstorming with given data we can find that,

Clearly,

All grocers are wrestlers follows.

Some wrestlers are grocers follows.

Some wrestlers are labourers follows.

Some labourers are grocers follows.

After analysing the given statements, the Venn diagram formed is,

Clearly, 

Some kind are sages follows.

Some kind are artists follows.

 

We can draw the following Venn diagram based on the statements:

Clearly, there are two possibilities, and even though all foolish (persons) being clever is a possibility, it is not a definite case. Therefore, it is not logically valid.

The foolish (persons) who are kings will definitely be clever as all kings are clever. Therefore, both II and III are logically valid.

Since some foolish (persons) are kings, we can definitely say that some kings are foolish (persons) and therefore, IV is also logically valid.

According to the question, Priyanka's mother is the only daughter of Saroj's mother. Assuming that Saroj is female, we can use the following family tree to represent this:

Thus, Saroj is the mother of Priyanka.

According to the question, the brother of the child's mother is the only son of Narendra's mother's father. i.e. the child's maternal uncle is the only son of Narendra's maternal grandfather. We can use the following diagram to represent this:

The child's maternal uncle is also the maternal's uncle of Narendra. Now, we cannot determine whether they are siblings or cousins because we do not know how many daughters their maternal grandfather has. Since 'cousin' is not one of the options, we can say that the child is Narendra's sister.

According to the given information, the lady in the photograph is the daughter of the daughter of the only son of Kaushal's grandfather.

So, the only son of Kaushal's grandfather is Kaushal's father. The daughter of Kaushal's father is Kaushal's sister. The daughter of Kaushal's sister is Kaushal's niece.

So, the following family tree can be drawn:

Therefore, the lady in the photograph is Kaushal's niece.

Hence, the correct answer is Niece.

According to the question, Manju is the wife of the only son of Gaurav's father's father.

The only son of Gaurav's father's father is Gaurav's father and therefore, Manju is the mother of Gaurav.

According to question

The only son of the maternal grandfather of the lady is the maternal uncle of the lady and this maternal uncle is the father of the brother of the man in photograph. Hence the man in the photograph is the maternal cousin of the lady.

As given equation is

$\Rightarrow$$13-12 ÷ 400 +20 \times 100$

After putting the actual signs for artificial signs

$\Rightarrow$$13$ $\times$ $12$$+$ $400$ $÷$ $20$$-$$100$

$\Rightarrow$ $156$ $+$ $20$$-$$100$

$\Rightarrow$$176$$-$$100$

$\Rightarrow$ $76$

The given equation is,

$12-4\times 7+8÷5$

After putting the actual signs for artificial signs,

$\Rightarrow 12÷4+7\times 8-5$

$\Rightarrow 3+56-5$

$\Rightarrow 54$

According to the given information:
$+$ means $\times$,
$\times$ means $+$,
$-$ means $÷$, and 
$÷$ means $-$, then 

The given expression is- $16\times 2÷4+7-8$

After replacing the coded signs with the actual ones, we get,

$16+2-4\times 7÷8=?$

$\Rightarrow 18-4\times \frac{7}{8}=?$

$\Rightarrow 18-\frac{7}{2}=?$

$\Rightarrow ?=\frac{36-7}{2}$

$\Rightarrow ?=\frac{29}{2}$

Hence, the correct answer is $\frac{29}{2}.$

The given expression is- $64+8÷6-4\times 2$

Replacing the coded signs with the actual signs, we get,

$64÷8-6\times 4+2=?$

$\Rightarrow 8-24+2=?$

$\Rightarrow ?=-14$

The given equation is,

$\Rightarrow 48\times 4÷7+8-2$

After putting the actual signs for artificial signs,

$\Rightarrow 12+7-16$

$\Rightarrow 3$

After brainstorming with given data, we find that there will be a talk on some particular fact. So, all the officers will assemble in the conference hall to attend the notice.

So only assumption I is implicit.

After brainstorming with the given data, we find that the bank can allow a person a loan of 1 lakh and above on collateral security for a certain period. So, Saroj may be granted a loan by the bank by mortgaging his house.

So, all three assumptions are implicit.

Given Statement: Training must be given to all the employees for increasing productivity and profitability.
After brainstorming with the given data, we can find that trained employees only can pay due attention to the policy of productivity and profitability. It is hard to expect profitability unless the employees pay attention to productivity. So these are supplementary to each other.

So. all three assumptions are implicit.

Hence, the correct answer is All are implicit.

After brainstorming with the given data, we can find that:
(1) The proposal for extending working hours would have been made with the consultation of all the members. 
(2) It became necessary to extend the working hours due to heavy load of work
On comparing these with the two given assumptions, it seems that only assumption II is implicit.

The fact that A wishes to conduct such a study the degree of effect of pay revision on job satisfaction of employees means the following:

The relation between pay scale revision and job satisfaction can be measured or estimated. A wouldn't be interested in conducting the study otherwise.
A has the capacity to study such a topic since he wouldn't have told B if he felt he is incapable of carrying out the work.

Therefore, both assumptions I and II are implicit.

According to the given information in the question, Raman is 14th from the right and 13th from the left. This means that there are 13 boys to the right of Raman and 12 boys to the left of Raman.

Total no. of boys = {(Raman’s place from the right) + (Raman’s place from the left)} — 1
Total no. of boys = 14 + 13 – 1 = 26

According to the given information in the question, Raman is 9th from downwards in a class. So, there are 8 students below Raman.

Total no. of students = {(Raman’s place from the top) + (Raman’s place from the bottom)} — 1
31 = Raman’s place from the top + 9 – 1
Raman’s place from the top = 31 – 9 + 1 = 23

Therefore, Raman’s is 23rd from upwards.

According to the given information in the question, Mohan is 21st from upwards in a class.

Total no. of students = {(Mohan's place from downwards) + (Mohan's place from upwards)} — 1

65 = (Mohan's place from downwards) + 21 – 1
Mohan's place from downwards = 65 – 21 + 1 = 45

Therefore, Mohan's place from downwards is 45th.

According to the given information in the question, Rohan is 11th from upwards and 27th from downwards among the boys who passed in a class. Also, it is given that 12 boys failed in the class.

Total no. of boys who passed = {(Rohan's place from downwards) + (Rohan's place from upwards)} — 1
Total no. of boys who passed = 27 + 11 – 1 = 37

Total no. of boys = Number of boys who passed + Number of boys who failed = 37 + 12 = 49

According to the given information in the question, we have to find out the total no. of boys in a line.

It is given that, Ganesh is 12th from the left and Rajan is 15th from the right. After interchanging their positions, Rajan is 20th from the right.
So, we know that Total no. of boys = {(Ganesh's first position) + (Rajan's second position)} - 1
Hence, Total no. of boys in a class = 12 + 20 - 1 = 31

When the digits are arranged in descending order, the number becomes 8765431.

After comparing 6315784 and 8765431, we can see that there are three pairs (7,8), (1,3) and (3,5), that has as many digits between them in the number as when the digits are rearranged in descending order.

Hence, the correct answer is three.

Given series,

7, 3, 9, 7, 0, 3, 8, 4, 6, 2, 1, 0, 5, 11, 13

When written in the reverse order :

13, 11, 5, 0, 1, 2, 6, 4, 8, 3, 0, 7, 9, 3, 7

Then 7th number from the left is 6 and 4th number to the right of 6 is 0.

According to given question

2 6 3 7 5 6 4 2 9 6 1 3 4 1 [6] 3 9 1 5 [6] 9 2 3 1 6 5 4 3 2 1 9 6 7 1 [6] 3

Hence only three 6s (in brackets) are there which are immediately preceded by 1 or 5 and immediately followed by 3 or 9.

According to given question

7 4 2 7 6 4 3 6 [7] 5 3 5 7 8 4 3 7 6 [7] 2 4 0 6 7 4 3

Hence only two 7s (in brackets) are there which are immediately preceded by 6 but not immediately followed by 4.

After rearranging 94316875 according to the directions in the question, the new number formed is 49138657.

The seventh digit from the left end of this new number is 5, and the third digit to the left of 5 is 3.
