Question

Find the time when simple interest on 1600 at 5% per annum is 480. ​

Answer 1

Answer:

time = 6 years

Step-by-step explanation:

SI= (p.t.r)

SI= 480

p=1600

r=5% = 5/100

t =?

480=(1600*5*t)/100

480=80*t

=> t=6 years

Answer 2

Answer:

it takes 6 years to get 480 as simple interest on 1600 at 5% per annum.

Step-by-step explanation:

Given that the principal amount is 1600 at an annual interest rate of 5% and the interest is 480. We have to find the time. So the equation that we are going to use is the simple interest formula.

That is,     $I=\dfrac{P\times R\times T}{100}$

Where 'I' is the total interst which is 480, 'P' is the principal amount which is 1600, 'R' is the  annual interest rate which is 5% and 'T' is the time in years which is we are looking for.

Now substitute the values in the equation,

    ∴  $480=\dfrac{1600\times 5\times T}{100}$

           $T=\dfrac{480\times 100}{1600\times 5}=6$

         

Rearrange the equation to find 'T'

Hence   $T=\dfrac{480\times 100}{1600\times 5}=6$

So the time $T=6$ years is the answer.
