Question 1
Five people J, H, I, F, and G are compared by Height and Age. i) F is older than I but shorter than H. ii) J is the tallest, but not the oldest. iii) G is older than J. iv) I is not the shortest, and H is the youngest. Who are the oldest and the shortest respectively?
Age: From (iii) J > F, and (ii) says F is not oldest, so J is oldest. Clue (iv) sets G as youngest. Also (i) gives I > H. A valid age order is G > J > F > I > H. Height: (ii) makes F tallest; (i) ensures G taller than I; (iv) H not shortest. A valid height order is J > I > H > F > G. Thus, oldest is G and shortest is G.
