Question

Find the simple interest on Rs.4000 for 5 years at 4% per annum.

Answer 1

Answer:

P=4000

T=5Y

R4%

$si = \frac{ptr}{100} \\ = \frac{4000 \times 5 \times 4}{1 00| } \\ = 800$

Answer 2

Answer:

Given :-

• A sum of Rs 4000 for 5 years at 4% per annum.

To Find :-

• What is the simple interest.

Formula Used :-

${\purple{\boxed{\large{\bold{S.I =\: \dfrac{P \times R \times T}{100}}}}}}$

where,

• S.I = Simple Interest
• P = Principal
• R = Rate of Interest
• T = Time

Solution :-

Given :

• Principal (P) = Rs 4000
• Rate of Interest (R) = 4%
• Time (T) = 5 years

According to the question by using the formula we get,

⇒ $\sf S.I =\: \dfrac{4000 \times 4 \times 5}{100}$

⇒ $\sf S.I =\: \dfrac{16000 \times 5}{100}$

⇒ $\sf S.I =\: \dfrac{80000}{100}$

⇒ $\sf S.I =\: \dfrac{\cancel{80000}}{\cancel{100}}$

➠ $\small\bf{\underbrace{\red{S.I =\: Rs\: 800}}}$

$\therefore$ The simple interest is Rs 800 .
