Among Q, R, S, T , U and V, who earns the highest salary?
I. T earns more than U but less than at least two persons, Q earns more than T but less than R.
II. S earns more than T but less than V, who is not the highest earner.
From I and II, R > Q > V > S > T > U OR R > V > Q > S > T > U OR R > V > S > Q > T > U Hence both are necessary to answer the question.
