Question

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

Answer 1

Answer:

49000

Step-by-step explanation:

P=28000

R=7.5% p.a.

T=10years

SI=(P*R*T)/100

=(28000*7.5*10)/100

=2800*7.5

=21000

Amount=P+SI

=28000+21000

=49000

Answer 2

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

• In this question, we are asked to find the amount for the give principal, rate and time.
• So, to find that, we have to first find the Simple Interest. Now, to find the Simple interest, we must use the formula :

$\sf S.I = \dfrac{p \times r\times t}{100}$

• After, finding the Simple Interest, we must add the Simple Interest with the Principal.

Given :

• Principal = Rs. 28000
• Rate = 7.5%
• Time = 10 years

To find :

• Amount

Solution :

Simple Interest = P × R × T/100

= 28000 × 7.5 × 10/100

= 28000 × 75/100

= 2100000/100

= 21,000

Therefore, Simple Interest is Rs. 21,000.

Now,

Amount = Principal + Simple Interest

= 28000 + 21000

= 49000

Therefore, Amount is Rs. 49000.
