Question

1) Find the simple interest on Rs. 800 borrowed for 4 years at 5 % p.a.​

Answer 1

Answer:

160

Step-by-step explanation:

SI=p×r×t/100

=800×5×4/100

=160

Answer 2

The simple interest will be Rs. 160

Given : Rs. 800 borrowed for 4 years at 5 % p.a.

To find : The simple interest.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the simple interest)

Here, we will be using the following mathematical formula.

Simple interest = (Principal amount × Rate of interest × Time)/100

Here,

• Principal amount = Rs. 800
• Rate of interest = 5% p.a.
• Time = 4 years

By, putting the available data in the above mentioned mathematical formula, we get :

Simple interest = (800 × 5 × 4)/100 = Rs. 160

(This will be considered as the final result.)

Hence, the simple interest will be Rs. 160
