Question
Simple interest is given by 
. If p = $1000, T = 3 years and R = 5%. Find the simple interest.
- 150
- 200
- 300
- 400
Hint:
We are given an algebraic expressions. An algebraic expression can consist of a variable and a constant. Values are assigned to the variables. We have to substitute the values and find the required quantity.
The correct answer is: 150
The given expressions is 
The value assigned are as follows:
P = $1000
T = 3 years
R = 5%
We are asked to find the value of simple interest or ‘I’.
To substitute the values, we will replace the variables by their values.
After substituting the values, we will perform the required operations.
So, the value of simple interest is 150.
We have to be careful about the operations because of the variables. We have to follow the proper procedure for performing the operations. The variables take different values under different conditions. So we have to be careful while substituting the values. The main part of this type of question is just replacing the variables by their values and performing the operation.
