Answer :
Answer:
To calculate the rate of interest, we can use the formula:
Interest = (Principal * Rate * Time) / 100
Given:
Principal (মূলধন) = 6570 টকা
Time (সময়) = 219 দিন
Interest (সুত্ৰ) = 2016.81 টকা
We can rearrange the formula to solve for the Rate (হাৰ):
Rate = (Interest * 100) / (Principal * Time)
Now, plug in the values:
Rate = (2016.81 * 100) / (6570 * 219)
Calculate the Rate to find the answer.
