Q. Ranjan goes 5 km towards North from a fixed point. Then he goes 3 km after turning to his right. After this he goes 5 km turning to his right. In the end he goes 4 km after turning to his left. How far and in what direction is he now from the fixed point?
A) 4 km, West
B) 7 km, East
C) 9 km, East
D) 7 km, West
E) None of these
Read Solution (Total 14)
-
- if consider fixed point is (0,0)
then he will be lastly at the point (3+4,0)=(7,0)
i.e 7 km away from origin in +ve X direction(EAST)
B) 7 km, East

- if consider fixed point is (0,0)
Then he goes 3 km after turning to his
right. After this he goes 5 km turning to his right. In the end he goes 4 km after turning to his
left
then he will be lastly at the point (3+4,0)=(7,0)
i.e 7 km away from origin in +ve X direction(EAST)
so answer will B) 7 km, East - 11 years agoHelpfull: Yes(7) No(0)
- here is a short cut for the direction sense problems
Opposite directions should be subtracted and same directions to be added
North East South East
5 3 5 4

noth-south=5-5=0
East + East= 3+4=7km east
answer is 7km east - 11 years agoHelpfull: Yes(3) No(0)
- none of these he goes 9 km west

- Suppose fixed point is X Ranjan goes 5 km north from X point
then goes right means east 3km, and then goes south 5km
so 5-5=0 so from fixed point X total linear distance is now 3km east
now ranjan again goes 4km in east side (by question)
so total distance=(3+4)km=7km in east from fixed point X.

- 7 km towards east
- 11 years agoHelpfull: Yes(0) No(0)
- E none of these.
Answer is 1 km west - 9 years agoHelpfull: Yes(0) No(0)
- Answer : 7 Km, East
North 5 Km, East, 3 Km, South 5 Km, East 3 Km
Net distance = 5N + 3E -5N + 4E = 7 Km
