Question
Six persons have different heights. T is shorter than at
most three persons. S is shorter than R but taller than T. W is immediate shorter than U. V is shorter than U. How many persons are taller than U?Solution
T is shorter than at most three persons. S is shorter than R but taller than T.
R > S > T 
W is immediate shorter than U. V is shorter than U.
R > S > T > U > W > V
 Final arrangement:
R (heaviest) > S > T > U > W > V (lightest)
