Solution
If two quantities x and y vary directly with each other, then `underlinebb(x/y "remains constant")`.
Explanation:
If two quantities x and y vary directly with each other, then `x/y` = k = constant.
Since, in direct proportion, both x and y increases or decreases together such a manner that the ratio of their corresponding value remains constant.
Hence, `x/y` remains constant.
