Question

If principal=2000 rate=5% per month time=146 days find the simple interest

Answer 1

Step-by-step explanation:

principal, P = 2000

rate, R = 5%

time, T= 146days

= 146/365 years

simple interest = (P×R×T)/100

= (2000×5×146/365)/100

=. (10000×146/365)100

=. (1460000/365)×1/100

=. 4000×1/100

= 40rupees

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\therefore{\text{Simple\:interest=40\:rupees}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{ \underline \bold{Given : }} \\ : \implies \text{Time (t)= 146\: days} \\ \\ : \implies \text{Principal(p) = 2000\:rupees} \\ \\ : \implies \text{Rate(r) = 5\%} \\ \\ \red{ \underline \bold{To \: Find: }} \\ : \implies \text{Simple\:interest(S.I) = ?}$

• According to given question :

$\bold{As \: we \: know \: that } \\ \circ \: \text{Simple \: interest} = \frac{ \text{Principal }\times \text{ Rate} \times \text{Time}}{100} \\ \\ \bold{Putting \: given \: values} \\ : \implies S.I = \frac{p \times r \times t}{100} \\ \\ : \implies S.I = \frac{2000 \times 5 \times\frac{146} {365} }{100} \\ \\ : \implies S.I = \frac{100\times146 }{365} \\ \\ \green{ : \implies \text{S.I= 40\: rupees}} \\ \\ \green{ \therefore \text{Simple\:interest =40\: rupees}} \\ \\ \bold{Basic \: formula\:related\:to\:C.I} \\ \circ \: A = p(1 + \frac{r}{100} )^{t}$
