Q:

What is the interest rate per annum, if a sum of money invested at compound interest amount to Rs. 2400 in 3 years and in 4 years to Rs. 2,520?

A) 3.5%	B) 4%
C) 5%	D) 6.5%

Answer & Explanation Answer: C) 5%

Explanation:

Let 'R%' be the rate of interest

From the given data,

$\frac{2520}{2400} = \frac{{(1 + \frac{R}{100})}^{4}}{{(1 + \frac{R}{100})}^{3}} \Rightarrow (1 + \frac{R}{100}) = \frac{63}{60} \Rightarrow R = 5$

Hence, the rate of interest R = 5% per annum.
