# 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

**Solution:**

Since the land is uniformly fertile the yield on it will vary directly with each other i.e. the more fertile the land is the more the yield is.

**✦ Try This:** Assuming the distance to be same, the time taken and speed will 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.

Since the distance is constant, as the speed increases the time taken to cover the distance will decrease. Hence time and speed will vary inversely with each other.
