Study the following information carefully and answer the questions given below:
Ritika starts walking from point A towards the east. After walking 7m, she reaches point B, from there she turns right and walks 2m to reach point C. Now she turns left and walks 9m to reach point E. Then she turns left again and walks 4m to reach point G. From there, she takes two consecutive left turns, walking 2m each, to reach point D. From there, she turns right and walks 6m to reach point K. Now finally she takes the right turn again and walks for 5m to reach Point L.
Four of the following five pairs are similar in a certain way. Which of the following pairs does not belong to the group?
- A.
Point A and Point B
- B.
Point B and Point D
- C.
Point C and Point E
- D.
Point K and Point D
- E.
Point E and Point G
Show answer & explanation
Correct answer: E
Concept
In a floor-plan / directions puzzle, after tracing the route on a grid each labelled point gets fixed (x, y) coordinates (east = +x, north = +y). Two points lie on the same straight line when they share one coordinate: equal y puts them on a horizontal (east–west) line, equal x puts them on a vertical (north–south) line. To find the odd pair out, plot every point and test which geometric property the majority of the given pairs share — the pair lacking that shared property is the answer.
Application — trace the route
Start at A (0, 0) facing east; walk 7 m east → B (7, 0).
Turn right (now facing south); walk 2 m → C (7, −2).
Turn left (now facing east); walk 9 m → E (16, −2).
Turn left (now facing north); walk 4 m → G (16, 2).
Two consecutive left turns, 2 m each: 2 m west to (14, 2), then 2 m south → D (14, 0).
Turn right (now facing west); walk 6 m → K (8, 0).
Turn right (now facing north); walk 5 m → L (8, 5).
Compare the pairs by coordinate
Read off the alignment of each given pair from its coordinates:
A (0, 0) & B (7, 0): equal y = 0 → horizontal line.
B (7, 0) & D (14, 0): equal y = 0 → horizontal line.
C (7, −2) & E (16, −2): equal y = −2 → horizontal line.
K (8, 0) & D (14, 0): equal y = 0 → horizontal line.
E (16, −2) & G (16, 2): equal x = 16 → vertical line.
Result
Four of the pairs share the same y-coordinate, so each of those lies on a horizontal (east–west) line. The pair E (16, −2) and G (16, 2) instead shares the same x-coordinate, so it lies on a vertical (north–south) line. Because it is the only pair with a different orientation, E and G is the pair that does not belong to the group.
