The average (arithmetic mean) of the even integers from 0 to 40 inclusive is how much greater than the average (arithmetic mean) of the even integers from 0 to 20 inclusive?
Pick:	A) 10	B) 20	C) 5	D) 30	E) 15
So, according to 10 mean of a set of even numbers from 0 to 40 =(0+40)/2= 
<gadget id="calculator">(0+40)/2</gadget>
<output>20</output>
20 and mean of a set of even numbers from 0 to 20=(0+20)/2= 
<gadget id="calculator">(0+20)/2</gadget>
<output>10</output>
10   Difference=20-10= 
<gadget id="calculator">20-10</gadget>
<output>10</output>
10   10nswer: 10.
<result>A</result>
The average (arithmetic mean) of the even integers from 0 to 40 inclusive is how much greater than the average (arithmetic mean) of the even integers from 0 to 20 inclusive?
