Difficulty: Easy
Correct Answer: 6000
Explanation:
Introduction / Context:
121% equals 1.21 as a multiplier. Multiply 5103 by 1.21 to get a value slightly above 6000. The options are coarse (thousands), so select the nearest thousand-level figure to the computed result.
Given Data / Assumptions:
Concept / Approach:
Decompose 1.21 into 1 + 0.21. Compute 0.21 * 5103 ≈ 1071.63, then add to 5103. Alternatively, compute 121/100 * 5103 directly and compare with choices.
Step-by-Step Solution:
Verification / Alternative check:
Among the coarse choices (4000, 6000, 8000, 10000), 6175 is only 175 away from 6000 but 1825 from 8000, so 6000 is the best approximation.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing 121% (1.21) with 0.121, which would reduce the value instead of increasing it.
Final Answer:
6000
