The difference between the simple interest received from two different sources on Rs.1500 for 3 years is Rs.13.50. The difference between their rates of interest is :
1). 0.1%
2). 0.2%
3). 0.3%
4). 0.4%
This is the right answer
Let r1, and r2 be the required
rate of interest
Then,
r1- r2 =$\frac{135}{450}$ = $\frac{27}{90}$
=0.3%
