• by checking the optins
  Amer invest : 40000
  Prem invest: 30000
  
  Amer: Prem:
  first year: first year:
  40000*(5/100)=2000 30000*(5/100)=1500
  end of first year=40000+2000=42000 end of first year=30000+1500=31500
  BUT 50% withdraw=40000/2=21000 But 11500 is withraw: 31500-11500=20000
  
  Second year: 21000*(5/100)=1050 Second year: 20000*(5/100)=1000
  total=21000+1050=22050 total=20000+1000=21000
  BUT 4050 IS WITHDRAWN
  END of second year=22050-4050=18000 Third year:21000*(5/100)=1050
  
  Third year:18000*(5/100)=900
  total=18900
  
  After 3 years Amer interest erned is 3950(2000+1050+900)
  
  ACCUMULATED AMOUNT OF AMER AT SECONDYEAR(1050)== ACCUMULATED AMOUNT OF PREM AT THIRD YEAR(1050)
