In Goshawk-Eurasian nature reserve 30 percent of the birds are Hawks, and 40 percent of the non-Hawks are Paddyfield-Warblers. If there are 25 percent as many Kingfishers as Paddyfield-Warblers in the reserve, then what percent of the birds in the nature reserve are not Hawks, Paddyfield-Warblers, or Kingfishers?	Pick:
A) 25% B) 35% C) 45% D) 70% E) 80%
Since the problem doesn't depend on the number of birds in reserve you can suppose that there are 100 birds.   From them  100*0.3=

<output>30</output>
30 are Hawks.So, there are 70 non-Hawks.   There are  0.4*70=

<output>28</output>
28 Paddyfield-Warblers. Therefore, there are   0.25*28= 
<gadget id="calculator">  0.25*28</gadget>
<output>7</output>
7 Kingfishers.   The total number of birds in the nature reserve that are not Hawks, Paddyfield-Warblers, or Kingfishers is  100-30-28-7=
