Answer 2

Answer:

The rate is $\frac {50} {9}$%

Step-by-step explanation:

Given:

Simple interest $75Rs$

$P=450Rs\\T=3 yrs$

Find: The rate per annum.

Solution:

Simple Interest: Simple interest is a method for calculating the amount of interest charged on a sum over a set period of time at a set rate. Unlike compound interest, where we add the interest of previous years' principal to compute the interest of the next year, the principal amount in simple interest is always the same.

$SI=\frac{P \times R \times T}{100}\\ 75=\frac{450 \times R \times 3}{100}\\ \frac{75 \times 2}{3 \times 9}=R$

$R= \frac {50}{9}$%

Hence, the Rate is $\frac {50}{9}$%
