Question

find the simple interest and the amount when principal = rs 6400,Rate=6% p.a. and time = 4 years
​

Answer 1

Answer:

SI = PRT/100

= 6400*6*4/100

= 153600/100

answer is rupees 1536

Answer 2

AnswEr :

• The simple interest = Rs. 1536.

• The amount = Rs. 7936.

Explanation :

We are given with the principal, rate and time, that is,

• Principal, P = Rs. 6400.

• Rate, R = 6%.

• Time, n = 4 years.

We have to find out the simple interest and amount.

Firstly we will find the simple interest.

As we are given with principal, rate and time.

We know that, if we are given principal, rate and time we have the formula, that is,

→ SI = PRT/100.

Substituting the given values in the formula,

⇒ SI = 6400 × 6 × 4/100

⇒ SI = 64 × 6 × 4

⇒ SI = 384 × 4

⇒ SI = 1536

Hence, the simple interest is Rs. 1536.

Now,

We will find the amount.

As we are given with principal and simple interest$.$

We know that, if we are given with principal and simple interest we have the required formula, that is,

→ Amount = Principal + Simple interest.

Substituting the given values in the formula,

⇒ Amount = 6400 + 1536

⇒ Amount = 7936

Hence, the amount is Rs. 7936.
