Question

what sum of money lent out 9% for 3 years will produce RS 81 simple interest? ​

Answer 1

Answer:

Using the formula,

Simple Interest = PRT/100

Given in the question,

R = 9%

T = 3 years

Simple Interest = Rs.81

Putting the values in the formula,

We get Principal amount (P) = Rs.300

So, the sum of money lent out = Rs.300

Hope it helps..!! ^_^

Answer 2

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is the rate of interest 9%.

Year =3 Years

Simple Interest =Rs81

 We need to find the Principal amount lent.

Thus, the formula of Simple Interest,

$SI=\frac{PRT}{100} \\SI\times 100=PRT\\P=\frac{SI\times 100}{RT}$

Now substitute the value in the above equation we get,

$P=\frac{81\times 100}{9\times 3} \\P=\frac{8100}{27}\\P=Rs.300$

Hence Rs.300 of money is lent.
