Answer 2

Answer:

Hence the sum of money lent is Rs.300

Step-by-step explanation:

In the above question, it is given that,

The given equation is the rate of interest 9%.

Time is 3 years,

SI is equal to Rs.81

 We need to find the sum of money lent that is the Principal amount.

Thus, the formula of Simple Interest is below,

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

Put the value in above equation we get,

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