In a class, except 18 all are above 50 years.15 are below 50 years of age. How many people are there

(a) 30 (b) 33 (c) 36 (d) none of these.

• As per given statements,
  15 are below 50 years of age.
  except 18 all are above 50 years. means 3 are of 50 years of age.
  
  there is no information about no of students above 50 years of age.
  
  so total no can not be determined.

• @sacreties ,
  
  pls check ur answer.
  
  X=no.of people above 50 years of age+no.of people below 50years of age
  so X=18+15=33 people
  
  You have taken 18 as no of people above 50
  whereas statement says
  except 18 all are above 50 years. so x-18 are above 50 years.
  
  pls excuse me if my interpretation is not correct.

• let X be the total no.of people
  X=no.of people above 50 years of age+no.of people below 50years of age
  so X=18+15=33 people
  hence option b is correct
