Answer 2

The rate of interest is 8%

Step-by-step explanation:

Principal = Rs.3125

Amount =Rs.3645

Time = 2 years

$A=P(1+r)^t\\3645=3125(1+r)^2\\\frac{3645}{3125}=(1+r)^2\\\sqrt{\frac{3645}{3125}}=1+r\\\sqrt{\frac{3645}{3125}}-1=r\\0.08=r$

Rate of interest = 8%

Hence the rate of interest is 8%
