That's the answer

Answer 2

Given:

• Principal = Rs. 660
• Rate = 4.5%
• Time = 3 years and 4 months = $\dfrac{10}{3}\:\sf{years}$

What to find?

We have to find the simple interest.

How to find?

To find the simple interest we will use the formula $\sf{SI=\dfrac{PRT}{100}}$ and substitute the value.

Solution:

Using the formula,

⇒ $\sf{SI=\dfrac{PRT}{100}}$

Substitute the values,

⇒ $\sf{SI=\dfrac{660\times 4.5\times10}{100\times 3}}$

Cancel the zeros in 660, 10 and 100,

⇒ $\sf{SI=\dfrac{66 \times 4.5}{3}}$

Divide 4.5 by 3,

⇒ $\sf{SI=66 \times 1.5}$

Multiply the numbers,

⇒ SI = Rs. 99

∴ So, the simple interest is Rs. 99.
