The starting numbers are:

    155 students enrolled; of them, 95 are males and the rest  155-95 = 60 are female.



By the end of the semester, 

    0.6*95 = 57  male are still enrolled and  0.4*60 = 24 female are still enrolled.



The number of those who still attend the class is  57 + 24 = 81 person.


Hence, the percentage of the originally enrolled students withdrawn from the class is


    {{{((155-81)/155)*100}}} = 47.74.     <U>ANSWER</U>
