D) 27.25kg
E) 34.25kg
total weight of(36+44) students=(36*40+44*35)= 
<gadget id="calculator">(36*40+44*35)</gadget>
<output>2_980</output>
2980kg.   Therefore weight of the total class=(2980/80)= 
<gadget id="calculator">(2980/80)</gadget>
<output>149/4 = around 37.25</output>
37.25kg.   Option 37.25kg
<result>C</result>
