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:
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
