$\underline\blue{Given\:that:-}$

Principal = Rs.6000

Amount = Rs.8700

Time = 9years

So, the interest = A - P

= 8700 - 6000

= Rs 2700

Now,

we have to find R %

$= > \frac{100 \times intrest}{p \times t}$

$= > \frac{100 \times 2700}{6000 \times 9}$

$= > \frac{270}{6 \times 9}$

$= > \frac{30}{6}$

$= > 5$

Hence, the rate is 5 % per annum
