Given :-

Principle amount deposited by Suhail = Rs. 8000

Annual interest rate = 18%

Time in years = 3 years

To Find :-

The interest he will get after the end of 3 years.

Solution :-

We know that,

a = Amount

p = Principle amount

r = Annual interest rate

t = Time

Using the formula,

\underline{\boxed{\sf Amount=P \bigg( 1+\dfrac{r}{100} \bigg)^t}}

Given that,

Principle (p) = Rs. 8000

Annual rate interest (r) = 18%

Time (t) = 3 years

Substituting their values,

⇒ a = 8000 × (1 + 18/100)³

⇒ a = 8000 × (118/100)³

⇒ a = 8000 × 1.18 × 1.18 × 1.18

⇒ a = 8000 × 1.64

⇒ a = 13120

Using the formula,

\underline{\boxed{\sf Interest = Amount - Principal }}

Given that,

Amount (p) = Rs. 13120

Principle (p) = Rs. 8000

Substituting their values,

⇒ 13120 - 8000

⇒ Rs. 5120

Therefore, interest he will get after the end of 3 years is Rs. 5120.
