Answer 1

Answer:

8100

I = P

$i = \frac{ptr}{100}$

=

$\frac{9000 \times 5 \times 18}{100}$

= 8100

Answer 2

Step-by-step explanation:

principal=9000

rate=18%

time=5year

Amount=P[1+R/100]ᵗ

A=9000[1+18/100]⁵

A=9000[118/100]⁵

A=9000[1.18]⁵

A=9000×1.18×1.18×1.18×1.18×1.18

A=20,589.8198112

Intrest=Amount-principal

intrest=20,589.8198112-9000

intrest=11,589.8198112≈11589.82rupees
