Of the 200 students at University XYZ majoring in one or more of the engineering disciplines, 130 are majoring in electrical and 150 are majoring in mechanical. If at least 30 of the students are not majoring in either electrical or mechanical, then the number of students majoring in both electrical and mechanical could be any number from Choose the correct choice from the following answers:
A) 30 to 70	B) 70 to 100	C) 110 to 130	D) 130 to 150	E) 150 to 170
lower point = Sum in each - total possible = 150+130- (200-30) = 280-170 =110...   higher point = entire 130 majoring in electrical major in mechanical too , so = 130..   range = 110 to 130   ANSWER:110 to 130
