ans me fast​

Answer 1

Answer:

Simple Interest= amount - principal

= 12000-9000

= Rs. 3000

$simple \: interest = \frac{time \times rate \times principal}{100} \\ \\ \\ = 3000 = \frac{3 \times rate \times 9000}{100} \\ \\ = rate = \frac{3000 \times 100}{3 \times 9000} \\ \\ = rate = \frac{300}{27} \\ \\ = rate = 11.111\%$
