• assume there are 100 students in the class.
  out of which 60%(given) are girls and 40%(100%-60%) boys.
  so there are 60 girls and 40 boys.
  25% of the girls are poor.
  therefore the probability that a poor girl selected as a leader ,out of 100 students is
  (25/100)*60=15
  15 girls are poor
  therefore (15/100)*100=15%
  ans:15%
