Answer:

P = 5000

A = 6000

T = 5 years

Let rate of CI = R%

\begin{gathered}A=P(1+ \frac{R}{100} )^t\\ \\ \Rightarrow 6000=5000(1+ \frac{R}{100} )^5\\ \\ \Rightarrow \frac{6000}{5000}= (1+ \frac{R}{100} )^5 \\ \\ \Rightarrow 1+ \frac{R}{100} =( \frac{6}{5} )^{ \frac{1}{5} }=1.037\\ \\ \Rightarrow \frac{R}{100}=1.037-1 = 0.037 \\ \\ \Rightarrow R=0.037 \times 100=3.7\end{gathered}

Answer:

4yr

Step-by-step explanation:

si= A-p

si=6000-5000

1000

si=p*t*r/100

1000=5000*t*5/100

1000= 50*t*5

t=1000/250

t=4
