Question

If two quantities x and y vary directly with each other, then-
(a)x/y remain constant (b)(x - y) remain constant
(C) (x + y) remain constant (d) x y remain constant​

Answer 1

Answer:

The correct answer is option (a)

Step-by-step explanation:

We know that if two quantity $x$ and $y$ vary directly with each other then

             $y=kx$, where k is a non zero constant

So clearly from above equation $\frac{x}{y}=k$, that mean x/y remain constant
