Directions: In the following question, there is a certain relationship between two given numbers on one side of (: :) and one number is given on the other side of (: :) while another number is to be found from the given alternatives having the same relationship with this number as the numbers of the given pair bear. Choose the best alternative.

4 : 24 : : 6 : ?

  1. 24

  2. 48

  3. 72

  4. 12

  5. 216


Correct Option: B
Explanation:

This is the correct option. This follows the correct pattern of x : x(x + 2). Here, if x = 4, then x(x + 2) = 4(4 + 2) = 4 * 6 = 24. If x = 6, then x(x + 2) = 6(6 + 2) = 6 * 8 = 48.

Directions: In the following question, there is a certain relationship between two given numbers on one side of (: :) and one number is given on the other side of (: :) while another number is to be found from the given alternatives having the same relationship with this number as the numbers of the given pair bear. Choose the best alternative.

  4. 1728

  5. 144


Correct Option: E
Explanation:

This is the correct option as it follows the correct pattern of x : (x + 1)2. If x = 9, then (9 + 1)2 = 100. If x = 11, then (11 + 1)2 = 144.

Directions: In the following question, there is a certain relationship between two given numbers on one side of (: :) and one number is given on the other side of (: :), while another number is to be found from the given alternatives having the same relationship with this number as the numbers of the given pair bear.

  3. 36

  4. 144

  5. 6


Correct Option: A
Explanation:

This is the correct option as it follows the correct relationship of x : x2/2, where x = 8 and x2/2 = 64/2 = 32. If x = 12, then 144/2 = 72.

Directions: In the following question, there is a certain relationship between two given numbers on one side of (: :) and one number is given on the other side of (: :) while another number is to be found from the given alternatives having the same relationship with this number as the numbers of the given pair bear.

  3. 64

  4. 512

  5. 729


Correct Option: C
Explanation:

This is the correct option as it follows the correct pattern of (x - 1)2 : (x + 1)2. So, if x = 4, then (4 - 1)2 = 9 and (4 + 1)2 = 25. If x = 7, then (7 - 1)2 = 36 and (7 + 1)2 = 64.
