Important Points

  •  संबंधित नहीं का अर्थ है "हमें एक ऐसा युग्म खोजना है जो दिए गए युग्म से अलग हो।"

 

  • यह अनुसरित तर्क इस प्रकार है: दूसरी संख्या = पहली संख्या × (पहली संख्या ÷ 2)
  • दिया गया है: 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

 

अतः, सही उत्तर "विकल्प 3" है।
