Consider the following diagrams:Q.x men, working at constant speed, do...
You can see it diagram wise (Technique 1) or mathematically (Technique 2).
Diagram I: Even for zero x, there exists some y (i.e. it assumes some value). This means, even if there are no men, there exist some working days, which is wrong.
Diagram II: If x is increased y is also increased. This means if no. of men are increased then the no. of working days increased, which is wrong.
Diagram III: This has two parts in it, a vertical line and a horizontal line. Vertical line suggests infinite working days for some number of workers, which is wrong. Horizontal line suggests, same working days even if the no of men is increased/decreased which is also wrong.
Diagram IV: This shows the correct relation i.e. no. of working days reduces as no. Of men are increased.
You can see this in terms of a mathematical equation too (Technique 2): Here x and y are inversely related. If x, the number of men increases, then, y, the number of days for completing the work decreases. So, mathematically they are inversely proportional. => x multiplied(1/y) => xy = constant This is an equation of a rectangular hyperbola which is shown in diagram IV.
