Question

To build a house a study was made comparing the number of workers with number of days it takes to build the house. According to it, with more number of workers it takes less number of days to build the house. What is the best possible relationship. G= No. of days. W=No. of workers.

• A. $G\left(W\right)=W^2$
• B. $G\left(W\right)=\sqrt{W}$
• C. $G\left(W\right)=W-3.5$
• D. $G\left(W\right)=\frac{45}{W}$

Answer 1

The correct option is D $G\left(W\right)=\frac{45}{W}$

It is given that the required number of days decreases with increase in the no of workers. Hence
$G\propto \frac{1}{W}$ or the relationship is $G=\frac{k}{W}$ where K is a constant. Hence option D satisfies the above type of relation.
