# ch.6 :- Direction Sense Test :- Introduction & Formula

✦  Directions for Q. No. 1 to 2 : Study the information and answer the questions given below:

On a playing ground Dev, Kumar, Nilesh, Ankur and Pintu are standing as directed below facing the North:
(i) Kumar is 40 m to the right of Ankur.
(ii) Dev is 60 m to the South of Kumar.
(iii) Nilesh is 25 m to the West of Ankur.
(iv) Pintu is 90 m to the North of Dev.

Ex. 1. Who is the North-East of the person, who is to the left of Kumar?

(a) Nilesh
(b) Ankur
(c) Dev
(d) Either Nilesh or Dev
(e) None of these

Sol.

From Fig. 6.2 it is very clear that the person to the left of Kumar is Ankur and Pintu is to the North-East of Ankur. Therefore, Pintu is our answer. But none of the options contain Pintu. Hence, option (e) is the correct answer.

Ex. 2. If a boy walks from Nilesh, meets Ankur followed by Kumar, Dev and then Pintu, how many meters has he walked if he has travelled the straight distance all through?

(a) 215 m
(b) 155 m
(c) 245 m
(d) 185 m
(e) None of these

Sol. Following the instructions as given in the question, the total distance covered by the boy
= 25 + 40 + 60 + 90 = 215 m
Hence, option (a) is the correct answer.

Ex. 3. Ankit started walking towards North. After walking 30 m, he turned towards left and walked 40 m. He then turned left and walked 30 m. He again turned left and walked 50 m. How far is he from his original position?

(a) 50 m
(b) 40 m
(c) 30 m
(d) 20 m
(e) None of these

From Fig. 6.3 the final position of Ankit is E and starting point is A. Therefore, he is only 10 m away from his starting point. Hence, option (e) is the correct answer.

Ex. 4. Lakshman went 15 km to the West from my house, then turned left and walked 20 km. He then turned East and walked 25 km and finally turning left covered 20 km. How far is he now from his house?

(a) 15 km
(b) 20 km
(c) 25 km
(d) 10 km

Sol.  Points A and E show the starting and end position respectively of Lakshman. It is clear that E is 10 km away from A. Hence option (d) is the correct answer.
