Select the number-pair from the given options where the first number is NOT related to the second number as in the given number-pair: 4 : 8

Select the number-pair from the given options where the first number is NOT related to the second number as in the given number-pair: 4 : 8 Correct Answer 3 : 9

Important Points

  •  NOT Related means "We have to find a pair that is different from the given pair."

 

  • The logic followed here is: Second number = First number × (First number ÷ 2)
  • Given: 4 : 8 ⇒ 4 × (4 ÷ 2) = 4 × 2 = 8
  1. 8 : 32 ⇒ 8 × (8 ÷ 2) = 8 × 4 = 32
  2. 2 : 2 ⇒ 2 × (2 ÷ 2) = 2 × 1 = 2
  3. 3 : 9 ⇒ 3 × (3 ÷ 2) = 3 × 1.5 = 4.5 ≠ 9
  4. 6 : 18 ⇒ 6 × (6 ÷ 2) = 6 × 3 = 18

 

Hence, "option 3" is the correct answer.
