Given
A+B+C=100
60A+40B+C=2000
Find A+B=?  Choose the most appropriate option
A) 76	B) 74	C) 40	D) 44	E) can't determine
(60A+40B+40=2000)-(A+B+40=100)   59A+39B=1900   So if we take A+B=40 so if A=17 and B=23 then 17+23=

<output>40</output>
40 and   59*17+39*23= 
<gadget id="calculator">  59*17+39*23</gadget>
<output>1_900</output>
1900   it satisfy the condition so correct answer is=40   ANSWER:40
<result>C</result>
