Question

find the amount for 3000 at 3.5% p.a simple interest 4.5 years​

Answer 1

Answer:

Amount =3472.5₹

Step-by-step explanation:

l=P×R×T/100

=3000×3.5×4.5/100

=472.5

Amount =P+l

Amount=3000+472.5

Amount=3472.5₹

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• To find the Amount, we must first find the Simple Interest. To find the Simple Interest, we must use the formula of :

$\sf Simple \: Interest = \dfrac{p \times r \times t}{100}$

• Next, we to find the Amount. We must use the formula of :

$\boxed{\sf Amount = Principal + Simple \: Interest }$

_______________

Given :

• Principal = Rs. 3000
• Rate = 3.5 %
• Time = 4.5 years

To find :

• Amount

Solution :

We know that,

$\sf Simple \: Interest = \dfrac{p \times r \times t}{100}$

                       $\sf = \dfrac{3000 \times 3.5 \times 4.5}{100}$

                       $\sf = \dfrac{30 \not 0 \not 0 \times 3.5 \times 4.5}{1 \not0 \not0}$

                       $\sf = \dfrac{30 \times 3.5 \times 4.5}{1}$

                       $\sf = \dfrac{30 \times 15.75}{1}$

                       $\sf = \dfrac{472.5}{1}$

                       $\tt = Rs. 472.5$

Therefore, Simple Interest is Rs.472.5.

Now,

Amount = Principal + Simple Interest

             = 3000 + 472.5

             = 3472.5

Therefore, Amount is Rs. 3472.5.
