Answer» After 6 boys were admitted and 6 girls left, the total number of students remained the same. Let X be the original number of girls and y be the original number of girls. Then, [(X + 6)/(X+ y) - (X / X+Y) ] * 100 = 75-60=> 600/(X+y) = 15=> X+y = 40 So, original number of boys = 60% of 40= (60/100)*40= 24. original number of girls = 40-24 = 16.
