Line Graph

Consider the following graph:


Which one of the following statements is not correct with reference to the graph given above?

  1. On 1st June, the actual progress of work was less than expected. 
  2. The actual rate of progress of work was the greatest during the month of August.
  3. The work was actually completed before the expected time. 
  4. During the period from 1st April to 1st September, at no time was the actual progress more than the expected progress.


On 1st June, actual progress was 25% and expected progress was 50%.

The slope of actual progress is steeper from August to September, hence rate was the greatest.

The correct option is D.
