## AAO Exam-CT 7: Reasoning (Order and Ranking)

0  65 Among P, Q, R, S, and T each scored different scores in the LIC AAO Pre examination. Q scored the highest marks. P did not qualify for the Mains while the other four cleared the Pre exam. The score of T is less than only two persons. S scored more marks than R.

Question:
If the cut-off mark to clear Pre exam is 72, then which of the following is the most possible score of R?
• 70
• 68
• 80
• 69
• 71

Persons: P, Q, R, S, and T

(1) Q scored the highest marks.

Q > ___ > ___ > ___ > ___

(2) P did not qualify for the Mains while the other four cleared the Pre exam.

Q > ___ > ___ > ___ > P

(3) The score of T is less than only two persons.

Q > ___ > T > ___ > P

(4) S scored more marks than R.

Thus, the final order is:

Q > S > T > R > P

If the cut-off mark to clear Pre exam is 72, we know that only P was not able to qualify.

Hence, the most possible score of R is 80.

Among P, Q, R, S, and T each scored different scores in the LIC AAO Pre examination. Q scored the highest marks. P did not qualify for the Mains while the other four cleared the Pre exam. The score of T is less than only two persons. S scored more marks than R.

Question:
If the score of T is 82 and Q is 93, then the score of S must be ______.
• 72
• 94
• 80
• 86
• 95

Persons: P, Q, R, S, and T

(1) Q scored the highest marks.

Q > ___ > ___ > ___ > ___

(2) P did not qualify for the Mains while the other four cleared the Pre exam.

Q > ___ > ___ > ___ > P

(3) The score of T is less than only two persons.

Q > ___ > T > ___ > P

(4) S scored more marks than R.

Thus, the final order is:

Q > S > T > R > P

If the score of T is 82 and Q is 93, then the score of S must be between 82 and 93.

Hence, 86 is the correct answer.

Among P, Q, R, S, and T each scored different scores in the LIC AAO Pre examination. Q scored the highest marks. P did not qualify for the Mains while the other four cleared the Pre exam. The score of T is less than only two persons. S scored more marks than R.

Question:
If R cleared the cut-off by one mark and P missed the cut-off just by 1 mark, then the difference between the marks of P and R is ___.
• 0
• 1
• 2
• None of these
• Can't be determined

Persons: P, Q, R, S, and T

(1) Q scored the highest marks.

Q > ___ > ___ > ___ > ___

(2) P did not qualify for the Mains while the other four cleared the Pre exam.

Q > ___ > ___ > ___ > P

(3) The score of T is less than only two persons.

Q > ___ > T > ___ > P

(4) S scored more marks than R.

Thus, the final order is:

Q > S > T > R > P

Let the cut-off mark be X.

If R cleared the cut-off by one mark and P missed the cut-off just by 1 mark, then

Marks of R = X + 1

Marks of P = X - 1

Difference between the marks of R and P = (X + 1) - (X - 1)

= X + 1 - X + 1

= 2

4. In a class of 45 students, a boy is ranked 20th. When two boys joined, his rank was dropped by one. What is his new rank from the end?
• 25th
• 26th
• 27th
• 28th
• 29th

Given data :

In a class of 45 students, a boy is ranked 20th

Total number of students = 45

When 2 new boys joined = 45 + 2 = 47

Now, total number of students = 47

Now, the rank of the boy dropped by 1 = 20 + 1 = 21st (Dropped means his rank is decreasing)

His new rank from the end = 47 - 21 + 1 = 27th

Hence, '27th' is the correct answer.

5. In a class of 60, the number of girls are twice that of boys. Kamal ranked seventeenth from the top. If there are nine girls ahead of Kamal, how many boys are behind him in rank?

• 3

• 7

• 12

• 23

• 11

Given statement;

Total strength of class = 60

Boys : Girls = 1 : 2

This means 20 boys and 40 girls are there in the class.

The rank of Kamal from the top is 17th.

which means 16 students are ahead of Kamal and nine are girls. So seven are boys.

Total boys = 20

Behind Kamal = 20 - 7 - 1(kamal) = 12 boys. (Kamal is a boy so he will also be counted

Hence, there are 12 boys behind kamal.

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

There are five persons Arvind, Sheela, Pranay, Shikha, and Satyam who has different heights. Shikha's height was more than only two people. Satyam's height was more than Sheela and Shikha but he was not the tallest. Arvind's height is more than Pranay's. The Second least height was 80cm.

Question:
Who was tallest among all?
• Satyam
• Arvind
• Sheela
• Shikha
• Pranay

1). Shikha's height was more than only two people.

_____>_____> Shikha > _____ > _____

2). Satyam's height was more than Sheela and Shikha but he was not the tallest.

_____> Satyam > Shikha > _____ > _____

Sheela can be in second last place or last.

3). Arvind's height is more than Pranay's.

Case 1: Arvind > Satyam > Shikha > Sheela > Pranay

Case 2: Arvind > Satyam > Shikha > Pranay > Sheela

Hence, Arvind is tallest.

Question:
If the height of tallest person is 130cm, Then what is the height of Shikha?
• 100cm
• 120cm
• 75cm
• None of these
• Cannot be determined

1). Shikha's height was more than only two people.

_____>_____> Shikha > _____ > _____

2). Satyam's height was more than Sheela and Shikha but he was not the tallest.

_____> Satyam > Shikha > _____ > _____

Sheela can be in second last place or last.

3). Arvind's height is more than Pranay's.

Case 1: Arvind > Satyam > Shikha > Sheela > Pranay

Case 2: Arvind > Satyam > Shikha > Pranay > Sheela

Hence, Shikha's height cannot be determined.

Note:

Since the height of Satyam is not know so we cannot decide what will be the possible height. If in the option only one option would have been between 80cm to 130cm then that could have a possible height of Shikha

9. Directions: Study the following information carefully and answer the questions that follow.

Each of the six stores P, Q, R, S, T, and U sold a different number of books in one day. Only three stores sold less books than U. P sold more books than R. T did not sell the highest number of books. S sold more books than R and P but less than U. The store which sold the second-highest number of books sold 72 books.

Question:
How many books did Q probably sell?
• 43
• 58
• 71
• 65
• 89

1) Only three stores sold less books than U

2) S sold more books than R and P but less than U

3) P sold more books than R

>   > U > S > P > R

4) T did not sell the highest number of books

Q > T > U > S > P > R

It is given that the store which sold the second-highest number of books sold 72 books. From above it is clear that store T sold the second-highest number of books. So, store Q sold the highest number of books.

By option, we can say store Q sold 89 books because 72 is the second highest.

10. Directions: Study the following information carefully and answer the questions that follow.

Each of the six stores P, Q, R, S, T, and U sold a different number of books in one day. Only three stores sold less books than U. P sold more books than R. T did not sell the highest number of books. S sold more books than R and P but less than U. The store which sold the second-highest number of books sold 72 books.

Question:
Which of the following stores sold the second lowest number of books?
• T
• P
• S
• R
• Q

1) Only three stores sold less books than U

2) S sold more books than R and P but less than U

3) P sold more books than R
