Number Analogy — Choose the pair that follows the same rule: 14 : 70 :: ____

Difficulty: Easy

Correct Answer: 75 : 375

Explanation:


Introduction / Context:
This is a numeric pair analogy. The first pair shows a multiplicative relation. We must find a second pair that mirrors exactly the same operation.


Given Data / Assumptions:

  • 14 : 70 means 70 = 14 * 5.
  • We seek a pair X : Y where Y = X * 5.


Concept / Approach:
Test each option with the “multiply by 5” rule and retain only the one that satisfies it precisely.


Step-by-Step Solution:

Check 75 : 375 → 75 * 5 = 375 ✔Check 15 : 90 → 15 * 6 = 90 ✘ (factor 6)Check 80 : 480 → 80 * 6 = 480 ✘ (factor 6)Check 19 : 57 → 19 * 3 = 57 ✘ (factor 3)


Verification / Alternative check:
Only option “75 : 375” preserves the exact multiplier 5.


Why Other Options Are Wrong:
They use different multipliers (3 or 6), breaking the analogy’s rule.


Common Pitfalls:
Picking any multiplicative pair without ensuring the same factor as the model pair.


Final Answer:
75 : 375
