What is the Simple Interest earned on Rs.2400 in 4 years 6 months at the rate of 4.5% per annum?

Correct option is C

Given:
Principle (P) = 2400
Rate (R) = 4.5
Time (T) = 4 years and 6 months = 4 + 1/2 = 9/2 years
As we know
Simple Interest = (P × R × T)/100
Solution:
Simple Interest = (2400 × 4.5 × 9/2 )/100 =486
Thus, the correct answer is (c).
