In an organisation with 1240 employees, 25% are promoted. How many employees got promoted?

Introduction / Context:
This is a direct percentage-of-a-number calculation. Find one quarter of 1240 (since 25% = 1/4).

Given Data / Assumptions:

• Total employees = 1240.
• Promoted = 25% of total.

Concept / Approach:
25% equals 1/4. Therefore, the number promoted is 1240 / 4. Alternatively, compute 0.25 * 1240.

Step-by-Step Solution:

Verification / Alternative check:
1240 / 4 = 310, consistent.

Why Other Options Are Wrong:
372 corresponds to 30%; 398 is 32.1%; 345 is ~27.8%; none match 25%.

Common Pitfalls:
Misplacing the decimal when applying percent to a four-digit number.

Final Answer:
310
