In a family of five members: P, Q, R, S, and T, each has a different favorite color: Red, Blue, Green, Yellow, and Black. P likes Blue. Q does not like Red or Black. R likes Green. What color does S like?
Answer: C. Yellow
Since P likes Blue, Q cannot like Red or Black, and R likes Green, the only colors left for S are Yellow and Red. Since Q cannot like Red, S must like Yellow.
