Difficulty: Easy
Correct Answer: 20
Explanation:
Introduction / Context:
We convert handicaps into scoring speed ratios, compare B and C, then project to the requested game length.
Given Data / Assumptions:
Concept / Approach:
From A:B = 3:2 and A:C = 5:4 ⇒ B:C = (2/3)/(4/5) = (2/3)*(5/4) = 10/12 = 5/6. C is faster than B (denominator smaller time for same points).
Step-by-Step Solution:
Verification / Alternative check:
Both frames (B finishing at 120 or C finishing at 120) are consistent with a 20-point handicap.
Why Other Options Are Wrong:
30/40/50 arise from mis-scaling or difference-based thinking rather than ratio-based.
Common Pitfalls:
Using absolute point gaps instead of relative scoring speeds when changing game length.
