1) 963

2) 942

3) 993

4) Can’t be determined

5) None of the above

Ans: 3

#### Solution:

Short cut formula:

The total number of persons is = Position of Pradip from the right ends + Position of Pradip from the left ends – 1

= 463 + 531 – 1 = 993

Hence, the total number of persons is 993.

Q.2. In a row all the persons are facing north, Rahul is 33rd from the left end and in the right side of Rahul, there are only 16 persons. Find out total number of person in this queue?

1) 49

2) 50

3) 51

4) Can’t be determined

5) None of these

Ans: 1

Solution:

Short cut formula: The total number of person is = Position of Rahul from the one of the ends + Number of person are there in the opposite direction of Rahul = 33 + 16 = 49

Hence, the total number of person is 49.

Q.3. In a row of 60 persons, Ganesh is 26th from left end. Find out his position from the right end.

1) 35

2) 36

3) 34

4) Can’t be determined

5) None of the above

Ans: 1

Solution:

Short cut formula: The total number of person =  Position of Ganesh from the right ends + Position of Ganesh from the left ends – 1

Now, Position of Ganesh from the right ends = The total number of person – Position of Ganesh from the left ends + 1

= 60 – 26 + 1 = 35.

Hence, Ganesh is 35th from the right ends.

Q.4. In a row, Yash is 15th from left end while Rima is 56th from right end and 16th to the right of Monu. Find out total number of persons of this queue?

1) 65

2) 83

3) 94

4) Can’t be determined

5) None of these

Ans: 4

Solution:

To find out the total member of a row we have to know the position of a person from the left end and the position of a person from the right end and there must be a relation among that two persons.

Here, the position of Yash and Rima are given but there is no relation among them.

Hence, the given data is not sufficient to answer this question.

Q.5. Siya is 18th from left end and 12th to the right of Rinku who is 38th from the right end. If all of them are facing north, Find out total number of persons in the row?

4) Can’t be determined

5) None of these

Ans: 2

Solution:

Rinku is 38th from the right end, it means there are 37 person to the right side of Rinku.

Siya is 18th from left end and 12th to the right of Rinku. It means there are 17 persons to the left side of Siya and there are 11 persons between Rinku and Siya in that row.

2) 39

3) Can’t be determined

4) None of these

5) 48

Ans: 1

Solution:

Here, the number of students is greater than the sum of the ranks of Ravi and Sarika.

Hence, the number of students in between Ravi and Sarika = 105 – (sum of the ranks of Ravi and Sarika)

= 105 – (36 + 41) = 28

Q7. In a batch of 100 students Kavya’s rank is 50th from the top and Lucky’s rank is 68th from the bottom. How many students are there in between Kavya and Lucky (if no two persons got the same rank)?

Solution:

Here, the number of students is less than the sum of the ranks of Kavya and Lucky.

Hence, the number of students in between Kavya and Lucky is

= (Sum of the ranks of Kavya and Lucky) – Total number of students – 2

= (50 + 68) – 100 – 2 = 16

5) Can’t be determined

Ans: 4

Solution:

Here, the number of persons between Gaurav and Tarun < The lowest positioned person (In this case, the position of Tarun was lowest i.e. 27th) – 1

Hence, Gaurav must be to the left side of Tarun.

Therefore, the number of person is = 29 + 27 + 26 = 82

2) 36th

3) 37th

4) 25th

5) Can’t be determined

Ans: 2

Solution:

From the left ends the position of Mahak is = 19th – 4th = 15th

Hence, the position of Mahak from the right end is = Number of Boys – position of Mahak from the left ends + 1

= 50 – 15 + 1 = 36th

Q15. In a row of Children facing north, K is 15th to the left of H, who is 22nd from the right end. If P is 14th from the left end and 6th to the right of K, how many children are there in that row?

1) 41

2) 38

3) 42

4) 44

5) None of the above

Ans: 4

Solution:

Here, P is 14th from the left end and 6th to the right of K. Hence, K is 8th from the left side.

Again, K is 15th to the left of H, who is 22nd from the right end.

Hence, K is 37th from the right side.

Therefore, the total number of Children is =

= K’s position from the right ends + K’s position from the left ends – 1

= 37 + 8 – 1 = 45 – 1 = 44

Q16. In a row, all are facing north, K is 28th to the left of H, who is 19th from the right end. If P is 6th from the left end then, how many people are there in that row?
