Question Statement:
In an evaluation of 150 tractors: 90 have power steering, 70 have air-conditioned cabs, and 60 have 4WD. 40 have both power steering and AC cabs, 35 have AC cabs and 4WD, and 45 have power steering and 4WD. If 25 tractors have all three features, how many tractors have EXACTLY ONE of these three features?
Options:
(A) 55
(B) 50
(C) 60
(D) 45
Answer Key:
A
Step-by-Step Solution & Explanation
Only PS $= 90 - (15 + 20 + 25) = 90 - 60 = 30$. Only AC $= 70 - (15 + 10 + 25) = 70 - 50 = 20$. Only 4WD $= 60 - (20 + 10 + 25) = 60 - 55 = 5$. Total exactly one $= 30 + 20 + 5 = 55$.
