U > Q > P > S > R > T Explanation - S is older than only T and R and R is not the youngest, T will be the youngest and Q is older than P but younger than U, according to this U is the oldest. Age of T is 28 years. Age of Q is 42 years as he is the second oldest and P is between Q and S so age of P will be 35 years of age.
