Question
Five friends, P, Q, R, S, and T, each have a different
number of pets. P has more pets than Q but fewer than T. R has fewer pets than Q. S is not the one with the most pets. Who has the most pets?Solution
P has more pets than Q but fewer than T, indicating T has more pets than P and Q. R has fewer pets than Q, placing R possibly at the lowest or just below Q in the count. S is not the one with the most pets, leaving T as the only option not disqualified from having the most pets. Therefore, T has the most pets.
