Simple Interest — What is the simple interest accrued in 4 years on a principal of ₹ 18,440 at 15% per annum?

Introduction / Context:
This is a direct application of the simple interest formula with clear principal, rate, and time.

Given Data / Assumptions:

• P = ₹ 18,440.
• r = 15% per annum.
• t = 4 years.

Concept / Approach:
Simple interest SI = P * r * t, with r as decimal (15% = 0.15).

Step-by-Step Solution:
SI = 18,440 * 0.15 * 4.0.15 * 4 = 0.60.SI = 18,440 * 0.60 = ₹ 11,064.

Verification / Alternative check:
Compute 10% of 18,440 = 1,844; 5% = 922; hence 15% per year = 2,766; in 4 years: 2,766 * 4 = 11,064.

Why Other Options Are Wrong:
Other values deviate from precise multiplication; they are plausible approximations but not exact.

Common Pitfalls:
Rounding mid-steps; here exact arithmetic yields a clean result.

Final Answer:
₹ 11,064
