Select the related numbers from the given alternatives.

23 ∶ 34 ∶∶ 47 ∶ ? 

1. 56
2. 60
3. 62
4. 69

Answer 1

Correct Answer - Option 3 : 62

The logic is:

23 ∶ 34 → 5² – 2 : (5 + 1)² - 2

Similarly,

47 ∶ ? → 7² – 2 : (7 + 1)²– 2

⇒ ? = 8² – 2

⇒ ? = 64 – 2

⇒ ? = 2

Hence, ‘62’ is the correct answer.
