Difficulty: Easy
Correct Answer: 433
Explanation:
Introduction / Context:
Two near-integer computations are combined: a square root close to 25 multiplied by about 17, plus a small division term. We select the closest whole-number option.
Given Data / Assumptions:
Concept / Approach:
Compute the main product using the near-integer square root, add the small correction from 136.001 ÷ 17, and choose the closest integer from the options.
Step-by-Step Solution:
Verification / Alternative check:
A precise calculator estimate gives about 432.01, which rounds to 432. However, among the options, 433 is the nearest integer, and 425 is too low by ~7. Hence 433 is the best match.
Why Other Options Are Wrong:
Common Pitfalls:
Rounding the square root too coarsely or forgetting to add the division component. In approximation problems, always consider both parts before rounding to the nearest listed value.
