General Mental Ability
Direction Sense Test
The problems in this chapter deal with the linear distance or displacement or direction between starting point and the final point in X – Y dimensions.
Example 1: One morning after sunrise, Sita and Gita were standing in a
chowk in Mumbai with their back towards each other. Sita’s shadow fell exactly
towards right hand side. Which direction was Gita facing ?
(a) East
(b) West
(c) North
(d) South
Solution: (c)
So, the answer is North.
Example 2: A girl was going towards west, then she turned left, then
turned 90° in clockwise direction. In which direction was she going now ?
(a) East
(b) West
(c) North
(d) None of these
Solution: (b)
So, the answer is West.
Example 3: Amit walks 2 km Northward and takes a left turn, walks 5 km
and then turns right, walks 3 km and again turning right, walks 5 km. In which
direction is he now from the starting point ?
(a) East
(b) North
(c) West
(d) South
Solution: (b)
So, answer is North.
Example 4: Sachin starts from his house and walks Westward. He then
takes a left turn and then a right, before each turn he walks 3 km. In which
direction is he walking now ?
(a) North
(b) South
(c) West
(d) East
Solution. (c)
So, answer if west.
Example 5: One morning Ram and Shyam were talking to each other
sitting opposite to each other. It was observed that Ram’s shadow fell to his
right. Then, which direction was he facing?
(a) East
(b) South
(c) North
(d) West
Solution. (b) Because Ram’s shadow is to his right it means that he is
facing the South. So, the answer is (b) South.
Example 6: Ragini starts fromher house towards East.
After walking a distance of 25 m, she turned towards left and walked 10 m. She
then turned right and after moving a distance of 20 m, turned to her right again
and walked 20 m. She then turns to the right and walks 7.5 m. Finally, she turns
to her right. In which direction is she walking now ?
(a) South-East
(b) West
(c) North
(d) North-West
Solution. (c) The movement is like
Hence, she is walking towards North. So, the answer is (c) North.
Example 7: Rakhi went 50 m towards the East, then turned right and
went 50 in. Rakhi again turned right and went 50 m. She took a 45° turn towards
her right and went straight. In which direction is she walking now?
(a) West
(b) North-East
(c) North-West
(d) North
Solution. (c) The movements are like
Hence, the answer is (c) North-West.
Example 8: Rati goes 10 kmWest, then turns left and goes 16 km. Then,
she turns right and goes 10 km and then she turns right and goes 16 km. At what
distance is she from the starting point now ?
(a) 16 km
(b) 12 km
(c) 14 km
(d) 20 km
Solution. (d) The movement is
The required distance OS is OP + PS, whereas PS = QR =10 km.
Hence, OS = 10 km + 10 km = 20 km. The answer is (d) 20 km.
Example 9: After going 60 m towards North, Tom takes a right turn and
goes another 16 m. He then takes a right turn and goes 48 m. How far is he from
the starting point ?
(a) 20 m
(b) 12 m
(c) 16 m
(d) 24 m
Solution. (a) Tom goes 60 m from W to X, then he goes 16 m from X to Y
and finally 48 m from Y to O. To find the distance
Example 10: Versha walks 20 m in West and then 20 m to the left. Now
every time turning to her right, she walks 10, 30 and 30 m respectively. How far
is she now from her starting point ?
(a) 30 m
(b) 10 m
(c) 40 m
(d) 20 m
Solution. (b) The movements of Versha are shown in figure and the
required distance is QL. Versha’s distance from starting point :
QL = OP – MN = (30 -20)m = 10 m
Hence, the answer is (b) 10 m.
Example 11: Dhiraj walks 50 m towards East. He then turns right and
walks 30 m. He again turns right and walks 50 m. Further, he moves 20 m. after
turning to the right. How far is he from his original position ?
(a) 50 m
(b) 30 m
(c) 20 m
(d) 10 m
Solution. (d) The movements of Dhiraj areas shown in figure and the
required distance is AE.
Hence, AE = BC – DE, ie, 30 m-20 m = 10m.
So, (d) is the answer.
Example 12: Aditi travels 10 km towards North. From there, she travels
4 km towards South. Then she travels 2.5 km towards East. How far is she from
the starting point ?
(a) 6.5 km
(b) 8.5 km
(c) 6 km
(d) 12.5 km
Solution. (a) Aditi travels 10 km from P to R, then travels 4 km from R
to S and finally 2.5 km from S to T. Therefore, the required distance is PT.
Example 13: After his office in the afternoon Rakesh goes facing the
sun. Then he turns to his left, then turn to his right and then turn to his
right and then to his left. In which direction is he moving ?
(a) North
(b) West
(c) East
(d) South
Solution. (b) The movement is like
Hence, he is moving in West direction. So, the answer is (b) West.
Example 14: The front door of my house faces East. I
walk out of my back door and walk 2 km, then turned right and walk another 2 km,
then turn left and walk 4 km and turn right again and walk 2 km. In which
direction am I facing with respect to starting point?
(a) South-West
(b) North-East
(c) North-West
(d) None of these
Solution. (c) The movement is like
Hence, the answer is (c) North-West.
Example 15: A girl is facing South. She turns 600 in the clockwise
direction and then turns 105° in the are ti-clockwise direction. In which
direction now she is facing ?
(a) South-East
(b) East
(c) North-East
(d) South-West
Solution. (a)
Clearly, the girl faces in the direction WX. On moving 60° in clockwise direction, she faces in the direction WY. On further moving 105° in anti-clockwise direction, she faces in the direction WZ. Hence, the girl is finally in South-East direction. Hence, answer is (a) South-East.
