Question
If a = 20 and b = 0, then what is the value of a × b?
- 20
- 10
- 0
- 200
Hint:
This is an algebraic expression. An algebraic expression consists of two components: a variable and a constant. A variable is a quantity that doesn't have a fixed value. It takes value as per the given conditions. It is generally denoted by an alphabet. A constant is a quantity with a fixed value. In the given question, values are assigned to the variables a and b. We have to find the final value after performing the operation.
The correct answer is: 0
The given expression is a × b.
In this question, values are assigned to a and b. We have to substitute the given values in the above expression and perform the operation. After performing the operation, we will get the final value.
The value of a is 20 and the value of b is 0. So we can write the above expression as follows:
a × b = (20) × (0)
The product of 20 gives zero, as any number multiplied with zero gives zero.
Therefore, the equation becomes
a × b = 0
So, the option (c), which is '0' , is the right option.
We have to substitute the value of variables as per given in the question. Under different conditions the value of variables is different.
