Question

Find the amount on Tk. 28,000 at the rate of 7.5% p. a. for 10 years.​

Answer 1

Answer:

Answer:

The amount on Tk. 28,000 at the rate of 7.5% p. a. for 10 years is Tk. 49,000.

Step-by-step explanation:

Given that:

Principal = Tk. 28,000

Rate = 7.5% p.a.

Time = 10 years

To Find:

What is the amount?

Formula used:

In Simple interest.

S.I. = (P × R × T)/100

A = P + S.I.

Where,

S.I. = Simple interest

A = Amount

P = Principal

R = Rate

T = Time

Finding the simple interest:

⟶ S.I. = (28000 × 7.5 × 10)/100

⟶ S.I. = 2100000/100

⟶ S.I. = 21000

∴ Simple interest = Tk. 21,000

Finding the amount:

⟶ A = 28000 + 21000

⟶ A = 49000

∴ Amount = Tk. 49,000

Answer 2

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

• Here, in this question, we are asked to find the Amount.
• So, to find the Amount, we must first find the Simple Interest. To find the Simple Interest, we must use the formula of :

$\boxed{ \tt Simple \: Interest = \dfrac{P \times R \times T}{100} }$

• Then, we must add the Simple Interest with the Principal

Given :

• Principal = 28,000
• Rate = 7.5%
• Time = 10 years

To find :

• Amount

Solution :

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

                            ${ \tt = \dfrac{28000 \times 7.5 \times 10}{100} }$

                            ${ \tt = \dfrac{28000 \times 75 }{100} }$

                            ${ \tt = \dfrac{280 \not0 \not 0 \times 75 }{1 \not 0 \not 0} }$

                            ${ \tt = \dfrac{280 \times 75 }{1} }$

                            ${ \tt = \dfrac{21000}{1} }$

                            $\tt = 21000$

Amount = Principal + Simple Interest

             = 28000 + 21000

             = 49000

Therefore, Amount is Rs. 49000.
