Question
Eight persons D, E, F, G, H, I, J and K standing in a
queue according to their height. D is fourth tallest person. J is taller than D. J is two persons taller than K. G is taller than both E and H. F is taller than G. H is two persons shorter than I. The number of persons taller than I is more than the number of shorter than G. How many persons are shorter than F?Solution
D is fourth tallest person. J is taller than D. J is two persons taller than K. J > _____ > K > D > _____ > ______ > _____ > _____ ….. (I) _____ > _____ > J > D > K > ______ > _____ > _____ ….. (I)  G is taller than both E and H. F is taller than G. H is two persons shorter than I. The number of persons taller than I is more than the number of shorter than G. Case 2 will get discarded. J > F > K > D > G > I > E > H ….. (I) _____ > _____ > J > D > K > I > _____ > H ….. (I) Therefore, the final arrangement is as follow: J(Tallest) > F > K > D > G > I > E > H(Shortest) Six persons are shorter than F.
