Question

what would be the simple interest obtained on an amount of rs 8930 at the rate of 8% per annum after 5 years ?​

Answer 1

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: SOLUTION \: \: } \mid}}}}}$

$\underline{ \huge{ \mathfrak{ \: \: Given : \mapsto \: }}} \\ \\ \: \: \: \: \: \: \: \: \: \: \mathtt{Principal , P = Rs. 8930} \\ \\ \: \: \: \: \: \: \: \: \: \: \mathtt{Rate \: \: of \: \: Interest, r = 8\%} \\ \\ \: \: \: \: \: \: \: \: \: \: \mathtt{No. \: \: of \: \: years, n = 5 \: years.}</p><p></p><p>$

$\huge{\underline{ \mathfrak{ \: \: To \: \: \: find : \mapsto}}} \\ \\ \: \: \: \: \: \: \text{Simple \: \: Interest \: \: obtains = ?}$

$\underline{ \mathfrak{ \: \: We \: \: know \: \: that, \: \: }} \\ \\ \: \: \: \: \: \mathtt{S.I. = \frac{ \: P \times r \times n \: }{ \: 100 \: } } \\ \\ \mathtt{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{8930 \times 8 \times 5}{100} } \\ \\ \mathtt{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{357200}{100} } \\ \\ \mathtt{\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3572}$

$\bold{Hence,} \\ \: \: \: \: \: \: \: \: \: \: \: \: \bold{The \: \: Simple \: \: Interest \: \: obtains \: \: on \: \: the \: \: } \\ \bold{amount \: \: Rs. \: 8930 \: \: at \: \: the \: \: rate \: \: of \: \: 8\% \: \: in \: \: 5 \: } \\ \bold{years \: \: is \: \: \underline{ \: \: Rs. 3572 \: \: }}$

Answer 2

We know that formula for simple intrest is PTR/100

where, P is the principal (money to be intrested)

T is the time in the form of number of years

and R is the rate of intrest per annum

So, according to this, our P is RS.8930, our T is 5 years and our R is 8%

So, PTR/100

=8930×8×5/100

=3572

So, a simple intrest of RS.3572 will be obtained on an amount of RS.8930 in 5 years at 8% per annum intrest.
