Question

p- 8000 S.I. = 1600 t = 4y r= ?​

Answer 1

Answer:

Step-by-step explanation:

Principal=8,000

Time=4 years

Rate=x

S.I=1600(given)

S.I=P*R*T/100

8000*x*4/100=1600

320x=1600

x=1600/320

=5

Therefore , the rate is 5 percent.

Answer 2

Given: $P = 8000, SI=1600, \ and\ t=4\ year$

We have to find the rate of interest.

As we know that the simple Interest of an amount is calculated by multiplying the interest rate by the principal amount and the time period.  

The formula is used to calculate the simple interest is:

$S I=\frac{P R T}{100}$

Where,

P = Principal Amount

T = Time in Years

R = Rate of Interest per Annum.

We are solving in the following way:

here,

$P = 8000, SI=1600, \ and\ t=4\ year$

Now,

$S I=\frac{P R T}{100}$

Putting the given values in the formula:

$=>1600=\frac{8000\times4\times R}{100} \\\\=>1600\times100=8000\times4\times R\\\\=>R=\frac{1600\times100}{8000\times4} \\\\=>R=5\%$

Hence, the rate will be$5\%$.
