Question
Answer the following questions based on the information
given below. Seven persons T, U, V, W, X, Y and Z has different weights. T is heavier than at least two persons. X is heavier than V, who is not the lightest. X is lighter than at least three persons. Z is heavier than W, is heavier T. U is heavier than at least five persons. U is not the heaviest. How many persons are heavier than Y?Solution
U is heavier than at least five persons. U is not the heaviest. ____> U > ____ > ____ > ____ > ____ > ____ X is lighter than at least three persons. ____> U > ____ > X > ____ > ____ > ____ ……. (I) ____> U > ____ > ____ > X > ____ > ____ ……. (II) X is heavier than V, who is not the lightest. T is heavier than at least two persons. Z is heavier than W, is heavier T. Case 2 will get discarded as we cannot place T. Z > U > W > X / T > T/X > V > Y ……. (I) Z > U > ____ > ____ > X > V > ____ ……. (II) Therefore, the final arrangement is as follow: Z (heaviest) > U > W > T/X> X/T > V > Y (lightest)
