Answer:

10%

Step-by-step explanation:

Given:-

Principle = p = 30, 000

Amount = 36, 300

Compound interest = 6, 300

Time = 2 years

Rate = ?

Solution:-

We know

Amount = P( 1 + r/100)ⁿ

Putting those values

⇒ 36300 = 30000(1 + r)²

⇒ 36300/30000 = (1 + r)²

⇒ 1.21 = (1 + r)²

⇒ √(1.21) = 1 + r/100

⇒ 1.1 = 100 + r/100

⇒ 110 + 100 + r

⇒ r = 10%
