Question 13

If two quantities x and y vary directly with each other, then
(a) $\frac{x}{y}$ remains constant
(b) x-y remains constant
(c) x+y remains constant
(d) $x \times y$ remains constant

Open in App

Solution

If two quantities x and y vary directly with each other, then
$\frac{x}{y} = k = c o n s t a n t .$

Since, in direct proportion, both x and y increases or decreases together in such a manner that the ratio of their corresponding value remains constant.
Hence, option (a) is correct.
