Of the diplomats attending a summit conference, 22 speak French, 32 do not speak Russian, and 20% of the diplomats speak neither French nor Russian. If 10% of the diplomats speak both languages, then how many diplomats attended the conference?
Choose the correct answer.
A) 72 B) 96 C) 100 D) 120 E) 150
{Total} = {French} + {Russian} - {Both} + {Neither}   {Total} = 22 + ({Total} - 32) - (0.1*{Total}) + 0.2*{Total}   Solving gives {Total} = 100.   Answer: 100.
