Q.16. Some students were standing in row facing north. Only Seema was

between Sumit and Ritu. Basant was exactly midway in the row. The number of

students to the left of Basant was equal to the cube of Kalka’s rank from the left end

and the number of student of the right of Basant was equal to square of Ashish’s

rank from the left end of the row. The number of students was less than 1000. How

man y students were there between kalika and Basant?

(1) 61

(2) 60

(3) 62

(4) Data Inadequate

(5) None of these

Answer: (2) 60

Let, Kalika’s rank from the left end = x

Ashish rank from the right end = y

No of students to the left of Basant = x3

No of students to the right of Basant = y2

Basant sit’s exactly midway in the row, so x3 = y2

Possible values of (x, y) = (1, 1), (4, 8) because number of total

students less than 1000

Kalika rank from the left end = 4th

Ashish rank from the left end = 8th

Total number of students between Kalika and Basant = (60 – 4) = 60.

Basant

Q.17. In a class among the passed students Babita is 22nd from the top and Sonu,

who is 5th ranks below Babita is 34th from the bottom. All the students from the class

appeared for an examination. If the ratio of the students who passed in the

examination to those who failed is 4: 1 for the class, how many students were there

in the class?

(1) Data Inadequate

(2) 70

(3) 75

(4) 60

(5) None of these

Answer: (3) 75

60

27

5

34th

22th

Bottom

Babita

Sonu

Babita’s rank from the top = 22nd

Sonu’s rank from the top = (22+5) = 27

Sonu’s rank from the bottom = 34th

So, Total students who passed the examination = (27 + 34) –

1 = 60,

Let the number of students passed = 4x and number of

students failed = x;

X = 60/4 = 15

So, total number of students in the class = 60 + 15 = 75.

Q.18. In a row of girls, Priyanka and Deepa occupy the ninth place from the right

9th 7

D/P D/P

Before Interchanging:

Priyanka’s rank from the right end = 9th

Deepa’s rank from the left end = 10th

After Interchanging:

Priyanka’s rank from the right = 17th

Deepa’s rank from the left = 18th

Total number of girls in the row = (10 + 17) – 1= 26

(1) 22

(2) 24

(3) 27

(4) 26

(5) None of these

Nataraja

n

Rangarajan Krishnarajan

→Dog Premrajan

Answer: (2) 24

On shifting 4 places to the left Komal is 10th from the left end of the row. Thus,

Komal’s original position was 14th from left end.

Swati is 3 places to right of Komal’s original position.

Clearly, Swati is 17th from the left end

Number of girls to the right of Swati = (40 – 17) = 23

Thus, Swati is 23 + 1 = 24th from the right end of the row.

Q.21.Amar is 16th from the left end in a row of boys and Vishal is 18th from the

right end. Ganesh is 11th from Amar towards the right and 3rd from Vishal towards the

right end. How many boys are there in the row?

(1) 45

(2) 26

(3) 39

(4) 41

(5) None of these

Answer: (4) 41

Vishal is 18th from the right end and Ganesh is 3rd to the right of Vishal. So, Ganesh

is 15th from the right end.

Clearly, there are 15 boys to the left of Amar; 10 boys between Amar and Ganesh and

14 boys to the right of Ganesh.

Hence, Total number of boys in the row = (15 + 1 +10 +1 +14) = 41

Q.22. In a row at a bus stop, A is 9th from the right and B is 7th from the left. They

both interchange their positions. If there are 20 people in the row, what will be the

new positions of B from the left?

(1) 11th

(2) 12th

(3) 13th

(4) 10th

(5) None of these

Answer: (1) 11th

Number of people in the row = position of person from the left + position of person

from the left – 1

A is 9th from the right. Also there are 20 people in the row.

So, 20 = position of left the left + 9 -1

Position of A form the left = 12th

When A and B interchange positions, A’s old position becomes B’s new position.
