Answer:
Option D, 72
Explanation:
Before touching the question, Let me tell you something about simple interest.
Simple Interest: It is something that is calculated for the additional amount paid on a loan amount. The formula for simple Interest is given by, SI = (P × R × T)/100 where, P specifies principal, R specifies rate, and T denotes time.
Now, Let's go for solving the question.
Simple Interest = P × R × T/100
0r, Simple interest = (720 × 5 × 2)/100
0r, Simple Interest = 72 × 2 × 5/10
0r, Simple Interest = 72
Hence, 72 is the required answer.
