Company workforce after attrition: A company has 724 employees. If 25% of them leave, how many employees remain?

Introduction / Context:
This is a straightforward percentage decrease problem: remove 25% of a total to find the remaining headcount.

Given Data / Assumptions:

• Total employees initially = 724.
• Percentage leaving = 25%.
• Remaining percentage = 75% of the original.

Concept / Approach:
Remaining = Initial * (1 − 0.25) = Initial * 0.75.

Step-by-Step Solution:

Verification / Alternative check:
25% of 724 = 181 (since 724/4 = 181). Subtract: 724 − 181 = 543.

Why Other Options Are Wrong:

• 550, 578, 565, 600 are not equal to 724 * 0.75.

Common Pitfalls:
Computing the number who left and forgetting to subtract from the original total, or rounding prematurely (here the value is exact).

Final Answer:
543
