Question

Assuming land to be uniformly fertile, the area of land and the yield on it vary

• A. directly with each other
• B. inversely with each other
• C. neither directly nor inversely with each other
• D. sometimes directly and sometimes inversely with each other

Answer 1

The correct option is A

directly with each other

If the land is uniformly fertile, then the area of land and the yield on it varies directly with each other.

If two quantities $x$ and$y$ increase or decrease in such a way that the ratio of their corresponding values remains constant, they are said to be in direct proportion.
