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.
