Question
What is the shortest distance between P and U?
Answer the questions based on the information given below. 'X @ Y (2m)' means 'X is 10m east of Y'. 'X $ Y (3m)' means 'X is 5m south of Y'. 'X % Y (7m)' means 'X is 17m north of Y'. 'X & Y (1m)' means 'X is 15m west of Y'. Certain number of persons sits at some distance. Q @ P (2m), R $ Q (3m), S @ R (2m), T % S (7m), U & T (1m)Solution
After decoding the given statements, we get, Q is 10m east of P. R is 5m south of Q. S is 10m east of R. T is 17m north of S. U is 15m west of T. The final arrangement is as follows: 
Shortest distance between P and U = √5² + 12² = √25 + 144 = √169 m = 13 m.
