Answer 1

Hello,

let students in each year be x , y , z
if 2000 students = 100 %
then, in Ist year,
          x=2000/110%
         x=100%/110%
        x=10/11
 in IInd year,
      y=2000/100%+10%+10%
     y=100%/120%
    y=5%/6%

 in IIIrd year,
     z= 2000/125%
     z=100%/125%
     z=0.8%

 in these 3 years, 
(0.90)% , (0.83)%, (0.8)%

 Hope i helped u
