Question

A sum of rupee 400 is lent for 3 years at the rate of 6 % per annum . Find the interest ​

Answer 1

Answer:

Step-by-step explanation:

Given,

Principal amount, P = Rs 400

Time period, T = 3 year

Rate of Interest, R = 6% p.a.

To Find,

Simple Interest, SI =?

Formula to be used,

Simple Interest = (P × T × R)/100

Solution,

We know that,

Simple Interest = (P × T × R)/100

Putting all the values, we get

⇒ Simple Interest = (400 × 3 × 6)/100

⇒ Simple Interest = 7200/100

⇒ Simple Interest = Rs. 72

Hence, the simple interest is Rs. 72.

Answer 2

Question:-

• A sum of rupee 400 is lent for 3 years at the rate of 6 % per annum . Find the interest .

To Find:-

• Find the simple interest.

Solution:-

Given ,

• Principle amount = 400

• Time period = 3 years

• Rate = 6%

Now ,

We have to find the simple interest:-

$\sf\dashrightarrow \: Interest = \dfrac { PTR } { 100 }$

$\sf\dashrightarrow \: Interest = \cancel\dfrac { 400 \times 3 \times 6 } { 100 }$

$\sf\dashrightarrow \: Interest = 4 \times 2 \times 3$

$\sf\dashrightarrow \: Interest = 72$

Hence ,

• Simple Interest is Rs.72
