Question

When A = 2, B = 4. Also, when A = 8, B = 1. What can be concluded about A and B?

• A. They are directly proportional.
• B. They are inversely proportional.
• C. A + B = Constant
• D. There is no relation between A and B.

Answer 1

The correct option is B They are inversely proportional.

Here, when A = 2, B = 4.
$\text{The product}A\times B=2\times 4=8$

Also when when A = 8, B = 1.
$\text{The product}A\times B=8\times 1=8$

Since the product is the same A and B are in inverse proprotion.
