A) Diagram I |
B) Diagram II |
C) Diagram III |
D) Diagram IV |
D) Diagram IV |
As the number of men increase the number of days taken to do the work mus: decrease which means that diagrams
II and III are ruled out. Moreover, the men work at constant speed which means that in no case will the work
be done in zero days no matter, how many men are put to work? Thus, diagram I is ruled out because. here the
graph touches the zero line on both the axes. Thus, the right answer is diagram IV.
