Difficulty: Easy
Correct Answer: 60
Explanation:
Introduction / Context:The counts of bowls are given per guest ratios. For G guests, the total bowls equal G/2 + G/3 + G/4. Setting this total to 65 yields a simple linear equation in G after taking a common denominator.Given Data / Assumptions:
Concept / Approach:Solve G/2 + G/3 + G/4 = 65. Use the common denominator 12 to combine terms and isolate G.
Step-by-Step Solution:
G/2 + G/3 + G/4 = (6G + 4G + 3G)/12 = 13G/12.13G/12 = 65 ⇒ 13G = 780 ⇒ G = 780/13 = 60.Verification / Alternative check:Compute bowls for G = 60: rice = 30, juice = 20, meat = 15; total = 65. Checks out exactly.
Why Other Options Are Wrong:
Common Pitfalls:Adding numerators without a common denominator or forgetting that each term depends on the same G.
Final Answer:
60
