Answer 1

S O L U T I O N :

$\underline{\bf{Given\::}}$

• Principal, (P) = Rs.8000
• Time, (T) = 2 years
• Rate, (R) = 5% p.a.

$\underline{\bf{Explanation\::}}$

As we know that formula of the Simple Interest;

$\boxed{\bf{S.I. = \frac{P \times R \times T}{100}}}$

A/q

$\mapsto\tt{Simple\:Interest = \dfrac{8000 \times 5 \times 2}{100} }$

$\mapsto\tt{Simple\:Interest = \dfrac{80\cancel{00} \times 5 \times 2}{\cancel{100}} }$

$\mapsto\tt{Simple\:Interest = Rs.(80 \times 5 \times 2)}$

$\mapsto\tt{Simple\:Interest = Rs.(80 \times 10)}$

$\mapsto\bf{Simple\:Interest = Rs.800}$

Now,

⇒ Amount = Principal + S.I.

⇒ Amount = Rs.8000 + Rs.800

⇒ Amount = Rs.8800

Thus,

The S.I. & amount of the Interest will be Rs.800 & 8800 .
