Question

Rs. 6500 is given at 7% per annum. Find the simple interest at the end of 3 years.​

Answer 1

Answer:

interest=100p∗r∗t

p = principal amount , r = rate , t = time

interest=1003500∗7∗2

interest = RS. 490

Answer 2

Given:

Principal = Rs. 6500

Rate = 7%

Time = 3 years

What to find?

We have to find simple interest.

How to find?

We have to use the formula $SI=\frac{PRT}{100}$ where SI stands for simple interest, P for principal, R for rate, T for time.

Solution:

Using the formula,

⇒ $SI=\frac{PRT}{100}$

Subtitute the value,

⇒ $SI=\frac{6500*7*3}{100}$

Cancel the zeros in 6500 and 100

⇒ SI = 65 × 7 × 3

Multiply the numbers,

⇒ SI = Rs. 1365

∴ So, simple interest is Rs. 1365.
