Difficulty: Easy
Correct Answer: 240
Explanation:
Introduction / Context:
This question combines two percentage calculations and asks for an approximate total. We compute each term to two decimals and then select the closest offered answer.
Given Data / Assumptions:
Concept / Approach:
Evaluate each percentage precisely enough to determine the nearest choice; do not average percentages directly, but convert each to actual numbers before summing.
Step-by-Step Solution:
Verification / Alternative check:
Rounding each component to two decimals (42.35 and 195.71) still sums near 238.06; the nearest among 225, 230, 240, 245 is 240 by a comfortable margin.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing 35% with 0.35 of 121 versus 35 of 121, or rounding prematurely on intermediate steps causing drift. Compute both terms then round the final total.
