Five years ago, Umar deposited RM7,200 in an account that gave 5.2% simple interest per annum. Find the total interest earned today.
The formula to calculate simple interest is:
Interest = principal * rate * time
In this case, the principal (P) is RM7,200, the rate (R) is 5.2%, and the time (T) is 5 years.
Calculating the interest earned:
Interest = 7200 * 0.052 * 5
Interest = 1872
The total interest earned today is RM1,872.
