Question

find the time in which rupees 6000 amount to rupees 8520 at 7% per annum

Answer 1

The time is 5 years.

Step-by-step explanation:

Given : Rupees 6000 amount to rupees 8520 at 7% per annum.

To find : The time ?

Solution :

Using compound interest formula,

$A=P(1+r)^t$

Where, A=Rs.8520 is the amount  

P=Rs.6000 is the principal

r is the interest rate r=7%=0.07

t is the time

Substitute the value,

$8520=6000(1+0.07)^t$

$\frac{8520}{6000}=(1.07)^t$

$1.42=(1.07)^t$

Taking log both side,

$\log(1.42)=t\log(1.07)$

$t=\frac{\log(1.42)}{\log(1.07)}$

$t=5.18$

Therefore, the time is approx 5 years.
