To find the interest and the rate of interest, we can use the formula for simple interest:
Simple Interest (SI) = Principal (P) * Rate (R) * Time (T)
In this case, the principal amount (P) is Rs 5600, the amount (A) after 5 years is Rs 8400, and the time (T) is 5 years. We need to find the rate of interest (R) and the interest itself (SI).
First, let's find the interest:
SI = A - P
SI = Rs 8400 - Rs 5600
SI = Rs 2800
The interest is Rs 2800.
To find the rate of interest, we can rearrange the formula:
R = SI / (P * T)
R = Rs 2800 / (Rs 5600 * 5)
R = 0.10 or 10%
The rate of interest is 10%.
Therefore, the interest is Rs 2800 and the rate of interest is 10%.
