Question

find I l=PTR/100 p=900 I=2 years R
=5%​

Answer 1

Given:

Principal (P) = Rs. 900

Rate (R) = 5%

Time (T) = 2 years

What to find?

We have the find the simple interest (SI) where principal (P) is Rs. 900, rate (R) is 5% and time (T) is 2 years.

How to find?

We can use the formula $SI=\frac{PRT}{100}$ to find the simple interest.

Solution:

By using the formula,

⇒ $SI=\frac{PRT}{100}$

By substituting the values,

⇒ $SI=\frac{900*5*2}{100}$

After cancelling the zeros from 900 and 100.

⇒ $SI=9*5*2$

After multiplying the numbers in RHS,

⇒ $SI=Rs. 90$

∴ So, the simple interest is Rs. 90.
