Answer 2

Explanation:

$\large\underline{\sf{Solution-}}$

Let assume that sum invested be $ P

Given that,

Simple interest (SI) received = $ 489.60

Rate of interest, r = 12 % per annum

Time period, n = 3 years

We know,

Simple interest (SI) received on a certain sum of money of $ P invested at the rate of r % per annum for n years is given by

$\boxed{ \sf{ \:SI \: = \: \frac{P \times r \times n}{100} \: }}$

On substituting the values, we get

$\sf \: 489.60 = \dfrac{P \times 12 \times 3}{100}$

$\sf \: 48960 = 12 \times 3 \times P$

$\sf \: 16320 = 12 \times P$

$\sf \: P = \dfrac{16320}{12}$

$\bf\implies \:P \: = \: 1360$

Hence,

$ 1360 will earn interest $ 489.60, if invested for 3 years at the rate of 12 % simple interest.
