At the college entrance exam, a candidate is admitted according to whether he has passed or failed the
test. Of the candidates who are really capable, 80 % pass the test and of the incapable, 25 % pass the test.
Given that 40 % of the candidates are really capable, then the proportion of the really capable students who
can pass the test to the total students who can pass is about

• If there are total 100 candidates, 40 candidates are really capable and 60 candidates are incapable.Of the candidates who are really capable, 32 pass the test and of the incapable, 15 pass the test.
  Total candidates who passed the test = 32+15=47
  the proportion of the really capable students who can pass the test to the total students who can pass = 32/47

• If there are total 100 candidates, 40 candidates are really capable and 60 candidates are incapable.Of the candidates who are really capable, 32 pass the test and of the incapable, 15 pass the test.
  Total candidates who passed the test = 32+15=47
  The really capable students = 32
  So the proportion of the really capable students who
  can pass the test to the total students who can pass is 32/47

• If there are total 100 candidates,
  40 candidates are really capable and
  60 candidates are incapable.
  Of the candidates who are really capable = 80%
  40*(80/100)=32 pass the test and
  of the incapable= 25%
  60*(25/100)=15 pass the test.
  Total candidates who passed the test = 32+15=47
  the proportion of the really capable students who can pass the test to the total students who can pass = 32/47.
