Answer 2

Answer:

A= Any number eg. 10

Step-by-step explanation:

The equation is true for all values of A . Otherwise, it is invalid equation.

From given equation,

A×120= 30×A×B

or, 120÷30=B ( Cancelling 'A' and dividing both sides by 30)

or, 40 = B

Now, substitute B=40 in the above equation, we get

A×120= 30× A× 40

or, A× 120= 120×A

or,A=A

However, the question is literally wrong.
