- A.
North South-west
- B.
South-east
- C.
North-west
- D.
North-east
Answer: Option
B
Explanation :
The position of the various people is as shown below:
Hence, E is to the South-east of D.
Hence, option (b).
7. CRE 1 - Basics | LR - Directions
How far (in km) is D away from A?
- A.
19
- B.
11
- C.
14
- D.
12
- E.
10
Answer: Option
E
Explanation :
Consider the solution to the first question of this set.
From the figure: DA2 = 62 + 82 = 36 + 64 = 100
∴ DA = 10 km
Hence, option (e).
8. CRE 1 - Basics | LR - Directions
How far (in km) is D away from E?
- A.
√450
- B.
21
- C.
√493
- D.
22
- E.
24
Answer: Option
C
Explanation :
Consider the solution to the first question of this set.
From the figure: DE2 = 182 + 132 = 324 + 169 = 493
∴ DA = √493 km
Hence, option (c).
Answer the next 2 questions based on the information given below:
A person walks towards the north, then moves to the right, then moves towards the north again. Now, the person moves towards the west, then north and finally takes a right turn again. What is the direction of the person w.r.t. the original position?
9. CRE 1 - Basics | LR - Directions

- A.
North
- B.
South
- C.
East
- D.
West
Answer: Option
C
Explanation :

Where is the person now w.r.t his starting position. Assume that the person travels an equal distance at each step
- A.
North
- B.
North-west
- C.
North-east
- D.
None of these
Answer: Option
A
Explanation :
Consider the solution to first question of this set.
