AAO Exam-CT 4: Reasoning (Alphabet Test)

1. Directions: Read the information carefully and answer the given questions: 

D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9 

Question:
Which of the following is 9th element to the left of the 17th element from the right end?
  • 5
  • @
  • A
  • F
  • None of these

2. Directions: Read the information carefully and answer the given questions: 

D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9 

Question:
If all the numbers are dropped from the arrangement, then which of the following will be thirteenth from the left end?
  • &
  • $
  • O
  • R
  • %

Given series:

Left End  D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9  Right End

After dropping all the numbers:

Left End  D F @ A # S % E G K & % O R $ L $ P B U %  Right End

Hence, the thirteenth element from the left end is O

3. Directions: Read the information carefully and answer the given questions: 

D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9 

Question:
Four of the following are alike in a certain way based on their positions in the above arrangement and so form a group. Which is the one that does not belong to that group?
  • F A #
  • 5 # 3
  • S 3 K
  • E K 9
  • & 1 O

Given series:

Left End  D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9  Right End

In each group, the pattern follows as:

Second element - First element = 1 (There is 1 element between the first and the second element of the group)

Third element - Second element = 2 (There are 2 elements between the third and the second element of the group)

Left End  D F @ A 5 2 # S % 3 E G K & % 1 9 7 O R $ 6 L $ P B 5 U % 9  Right End

Only in the 4th option, E K 9, there are 3 elements between K and 9

Hence, E K 9 does not belong to the group

4. If in the number '67843624' digits which is/are less than 5 subtracted by one and digits greater than 5 added by one then what is the value of the sum of non repeated digits?
  • 10
  • 12
  • 17
  • 23
  • 20

Given: 67843624

digits less than 5 subtracted by one and digits greater than 5 added by one then,

Given 6 7 8 4 3 6 2 4
Operation +1 +1 +1 -1 -1 +1 -1 -1
New number 7 8 9 3 2 7 1 3

 

So, Non repeated numbers are 8, 9, 2, 1.

Sum of 8+ 9+ 2+ 1= 20,

Hence,  20 is the sum of non repeated numbers.

5. How many such pairs of letters are there in the word ‘DISCHARGE’, each of which has as many letters between them in the word (both forward and backward direction) as they have between them in the English Alphabet?
  • One
  • Two
  • Three
  • None
  • More than three

6. If it is possible to make a meaningful word with the 2nd, 3rd, 5th and 6th letters of the word “ALGORITHM”, which of the following will be the second letter of that word? If more than one such word can be formed, give 'X' as the answer and if no such word can be formed, give 'Y' as the answer.

  • G
  • I
  • R
  • X
  • Y

Given- ALGORITHM

2nd, 3rd, 5th and 6th Letters are- L, G, R, I

Meaningful word is- GIRL.

Hence, Second letter of the word is I.

7. Direction: Answer the questions based on the information given below: 472 209 593 196 765

Question:
If the second and third digit of each number is interchanged then how many new numbers will be perfect squares?None
  • None
  • One
  • Two
  • Three
  • Four

Given numbers: 472 209 593 196 765

On interchanging second and third digit of each number: 427 290 539 169 756

So, only 169 is a perfect square. Hence, ‘one’ is the correct answer.

8. Direction: Answer the questions based on the information given below: 472 209 593 196 765

Question:
How many numbers are there in between the square of the third digit of the third number and the square of the first digit of the first number?
  • Three
  • Four
  • Five
  • Six
  • More than Six

Given numbers: 472 209 593 196 765

The square of the third digit of the third number = 32 = 9

The square of the first digit of the first number = 42 = 16

Numbers between 9 and 16 is 10, 11, 12, 13, 14 and 15. Hence, ‘six’ is the correct answer.

9. Direction: Answer the questions based on the information given below: 472 209 593 196 765

Question:
The sum of first and fourth number is how much greater than twice the second number?
  • 50
  • 150
  • 250

  • 350
  • None of these

Given numbers: 472 209 593 196 765

Sum of first and fourth number = (472 + 196) = 668

Twice of second number = 2 × 209 = 418

Difference = 668 – 418 = 250 Hence, ‘250’ is the correct answer.

10. Direction: Answer the questions based on the information given below: 472 209 593 196 765

Question:
Which of the following number leaves a remainder 5 when divided by the square root of the only perfect square given in the arrangement?
  • 472
  • 209
  • 593
  • 765
  • None of these

Given numbers: 472 209 593 196 765

196 is the only perfect square and 14 is the square root of 196.

1. 472 → 472 ÷ 14, Remainder = 10

2. 209 → 209 ÷ 14, Remainder = 13

3. 593 → 593 ÷ 14, Remainder = 5

4. 765 → 765 ÷ 14, Remainder = 9 Hence, ‘593’ is the correct answer.
