All the roads of a city are either perpendicular or parallel to one another. The roads are all straight. Roads A, B, C, D and E are parallel to one another. Roads G, H, I, J, K, L and M are parallel to one another.
(i). Road A is 1 km east of road B.
(ii). Road B is ½ km west of road C.
(iii). Road D is 1 km west of road E.
(iv). Road G is ½ km south of road H.
(v). Road I is 1 km north of road J.
(vi). Road K is ½ km north of road L.
(vii). Road K is 1 km south of road M.
If road E is between B and C, then distance between A and D is :
Clearly from statements (1) and (2), figure 1 follows; from statement (3), figure 2 follows; from statement (4), figure 3 follows; and from statement (5), figure 4 follows; and from statements (6) and (7), figure 5 follows.
From the figure in Q. 50, the distance between A and D
= AB + ED - BE = (1 + 1 - ¼) = 2 - .25 i.e. between 1.5 to 2 km.
