Question

if p = ₹ 400 R = 5 % time = 3 years find simple interest​

Answer 1

Answer:

Given :-

• A sum of ₹ 400, rate of interest is 5% and time period is 3 years.

To Find :-

• What is the simple interest.

Formula Used :-

$\clubsuit$ Simple Interest or S.I. Formula :

$\bigstar \: \: \sf\boxed{\bold{\pink{Simple\: Interest =\: \dfrac{P \times R \times T}{100}}}}\: \: \: \bigstar$

where,

• P = Principal
• R = Rate of Interest
• T = Time Period

Solution :-

Given :

• Principal = ₹ 400
• Rate of Interest = 5%
• Time Period = 3 years

According to the question by using the formula we get

$\implies \bf Simple\: Interest =\: \dfrac{P \times R \times T}{100}$

$\implies \sf Simple\: Interest =\: \dfrac{400 \times 5 \times 3}{100}$

$\implies \sf Simple\: Interest =\: \dfrac{400 \times 15}{100}$

$\implies \sf Simple\: Interest =\: \dfrac{60\cancel{00}}{1\cancel{00}}$

$\implies \sf Simple\: Interest =\: \dfrac{60}{1}$

$\implies \sf\bold{\red{Simple\: Interest =\: ₹\: 60}}$

$\sf\bold{\purple{\underline{\therefore\: The\: simple\: interest\: is\: ₹\: 60\: .}}}$

Answer 2

Question :-

• Find the Simple Interest , when Principal is Rs. 400 , Rate of Interest is 5 % and Time Period is 3 years .

Answer :-

• Simple Interest = Rs. 60

$\rule {180pt}{2pt}$

Given :-

• Principal = Rs. 400
• Rate of Interest = 5 %
• Time Period = 3 years .

To Find :-

• Simple Interest = ?

Solution :-

As per the provided information in the given question, it is given that Principal is Rs. 400 . Rate of Interest is 5 % . Time Period is 3 years . And, we have been asked to calculate the Simple Interest .

For calculating the Simple Interest , formula required :-

• $\bf{ Simple \: Interest \: = \: \frac{P \times R \times T}{100} }$

Where,

• P denotes to Principal
• R denotes to Rate of Interest
• T denotes to Time Period

Therefore, by substituting the given values in the above Formula :-

$\dag \: \: \sf{Simple \: Interest \: = \: \frac{P \times R \times T}{100}}$

$\Longrightarrow \: \: \sf{Simple \: Interest \: = \: \frac{400 \times 5 \times 3}{100} }$

$\Longrightarrow \: \: \sf{Simple \: Interest \: = \: \frac{4 \times 5 \times 3}{1} }$

$\Longrightarrow \: \: \sf{Simple \: Interest \: = \: 4 \times 5 \times 3}$

$\Longrightarrow \: \: \textbf{\textsf{Simple \: Interest \: = \: 60}}$

Hence :-

• Simple Interest = Rs. 60
