Data interpretation & sufficiency Easy

Consider the following graph:

Line graph of % of work (0–100%) from 1st April to 1st September. The dashed ‘Expected progress’ line reaches about 25% by May, 50% by June, about 70% by August and 100% on 1st September; the solid ‘Actual progress’ line rises slowly to about 42% by August, then climbs steeply, crosses above the expected line and reaches 100% before 1st September.
From UPSC's question paper.

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

Answer & explanation

Answer: (d) During the period from 1st April to 1st September, at no time was the actual progress more than the expected progress.

In August the actual-progress line shoots up, crosses above the expected line and reaches 100% before 1st September. So for a while actual progress did exceed expected progress, which makes statement (d) the incorrect one.

  1. (a) On 1st June actual progress is about 22% against an expected 50% — true.
  2. (b) The actual line is steepest in August, rising from about 42% to 100% — true.
  3. (c) Actual progress reaches 100% during August, before the expected finish on 1st September — true.
  4. (d) In late August the actual line crosses above the expected line, so actual progress was more than expected for a time — false.
  5. The statement that is not correct is (d).

Remember · In 'not correct' graph items, test every option against the picture, and look closely where two lines cross.
