Question

if principal =Rs 8000, period =5 years,rate=7p.c.p.a find the simple intrest and amount​

Answer 1

Answer:

P×R×T/100 =8000×7×5/100=2800ans

Answer 2

Given:

If principal = Rs 8000, period = 5 years, rate = 7 p.c.p.a

To find:

The simple interest and amount​

Solution:

The sum of money, P = Rs. 8000

The rate of interest, R = 7 % p.a.

The no. of years, T = 5 years

We know,

$\boxed{\bold{Simple \:Interest = \frac{P\times R \times T}{100} }}\\\\\boxed{\bold{Amount = Principal + Simple \:Interest }}$

By using the formula above, we get

The simple interest is,

= $\frac{8000\: \times \:7 \: \times \: 5}{100}$

= $80\: \times \:7 \: \times \: 5$

= $\bold{2800}$

and

The amount is,

= $8000 + 2800$

= $\bold{10800 }$

Thus,

$\boxed{\bold{Simple\:Interest \rightarrow \underline{Rs. \:2800} }} \\\\\boxed{\bold{Amount \rightarrow \underline{Rs. \:10800} }}$
