Ipshita started walking from Point A in the west direction for 3m and reached Point B. From Point B, she turned left and walked 7m to reach Point R. From Point R, she turned right and walked 5m to reach Point K. From Point B, she turned right and walked 7m to reach Point C. From Point C, she turned left and walked 8m to reach Point D. From Point F, she turned right and walked 7m to reach Point G. From Point D, Ipshita turned right and walked 9m to reach Point E. From Point E, she turned right again and walked 7m to reach Point F. From Point G, she turned left and walked 4m to reach Point I. From Point K, she turned right and walked 5m to reach Point L. From Point H, she turned right and walked 5m to reach Point O. From Point A, she turned left and walked 3m to reach Point H.

Four of the following five pairs are similar in a certain way. Which one does not belong to the group?

Question

Ipshita started walking from Point A in the west direction for 3m and reached Point B. From Point B, she turned left and walked 7m to reach Point R. From Point R, she turned right and walked 5m to reach Point K. From Point B, she turned right and walked 7m to reach Point C. From Point C, she turned left and walked 8m to reach Point D. From Point F, she turned right and walked 7m to reach Point G. From Point D, Ipshita turned right and walked 9m to reach Point E. From Point E, she turned right again and walked 7m to reach Point F. From Point G, she turned left and walked 4m to reach Point I. From Point K, she turned right and walked 5m to reach Point L. From Point H, she turned right and walked 5m to reach Point O. From Point A, she turned left and walked 3m to reach Point H.

Four of the following five pairs are similar in a certain way. Which one does not belong to the group?

Accepted Answer

**Solution:**

1. First, plot the points and directions based on the given movements:
   - From A, Ipshita walks 3m west to B.
   - From B, she turns left (south) and walks 7m to R.
   - From R, she turns right (west) and walks 5m to K.
   - From B, she turns right (north) and walks 7m to C.
   - From C, she turns left (west) and walks 8m to D.
   - From D, she turns right (north) and walks 9m to E.
   - From E, she turns right (east) and walks 7m to F.
   - From F, she turns right (south) and walks 7m to G.
   - From G, she turns left (east) and walks 4m to I.
   - From A, she turns left (south) and walks 3m to H.
   - From H, she turns right (west) and walks 5m to O.
   - From K, she turns right (north) and walks 5m to L.

2. Now, analyze the pairs:
   - I-F: Distance between I and F is 4m (east-west direction).
   - C-G: Distance between C and G is 7m (north-south direction).
   - O-D: Distance between O and D is 13m (west-east direction).
   - H-E: Distance between H and E is 12m (south-north direction).
   - F-R: Distance between F and R is 14m (east-west direction).

3. Notice that all pairs except O-D are either directly connected or have distances that are multiples of 7 or 4, and they lie on the same straight line segments or are closely related in the path.

4. The pair O-D stands out because the distance is longer and they are not directly connected or aligned similarly as the others.

**Answer:** (c) O-D
