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.

36 : 125 : : 25 : ?

  1. 64

  2. 16

  3. 36

  4. 11

  5. 26


Correct Option: A
Explanation:

This is the correct answer as it follows the correct relationship x: (x - 1)y + 1, i.e. 6= 36, (6 - 1)2 + 1 = 125. So, if x = 5 and y = 2, then x= 52 = 25 and (x - 1)2 + 1 = (5 - 1)2 + 1.

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.

  1. 7

  2. 37

  3. 36

  4. 9

  5. 21


Correct Option: E
Explanation:

This is the correct answer as it follows the correct relationship. 3x : 3x + 3, i.e. x = 5, 3x = 3 * 5 = 15 and 3x + 3 = 3 * 5 + 3 = 18 So, if x = 6, then 3x = 3 * 6 = 18 and 3x + 3 = 3 * 6 + 3 = 21.

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.

  1. 17

  2. 16

  3. 4

  4. 65

  5. 18


Correct Option: D
Explanation:

This is the correct answer as it follows the correct relationship x: x+ 1, i.e. x = 3, x= 27 and x+ 1 = 28.

So, if x = 4, then x= 64 and x+ 1 = 65.
