Hi try this :

 BMI=input(' Enter BMI : ');

 if(BMI<18.5)
   classification='underweight' 
 elseif(18.5<BMI && BMI<24.9) 
 classification='Normal weight' 
  else(25<BMI && BMI<29.9)
 classification='Overweight' 
end

How about obese for BMI greater than 30?

if BMI < 18.5
  classification='underweight'
elseif 18.5 <= BMI && BMI < 24.9
  classification='Normal weight'
elseif 24.9 <= BMI && BMI < 30
  classification='Overweight'
else
  classification='Obese'
end
