DIRECTIONS : Questions based on directions are of set patterns and hence follows set of rules.
| 16. | A walks 10 metres in front and 10 metres to the right. Then every time turning to his left, he walks 5, 15 and 15 metres respectively. How far is he now from his starting point? | ||
|---|---|---|---|
| A. 5 metres C. 15 metres | B. 10 metres D. 20 metres | ||
| Ans : A. The movements of A are as shown in figure . ( O to P, P to Q, Q to R, R to S and S to T).Since TS = OP + QR, so T lies in line with O = OT = (RS - PQ) = (15 - 10 ) m = 5 m. | |||
| 17. | A man walks 30 metres towards South. Then I turn right again and walks 30 metres. Then, turning to his left, he walks 20 metres. Again, he turns to his left and walks 30 metres. How far is he from his initial position? | ||
|---|---|---|---|
| A. 20 metres C. 60 metres | B. 40 metres D. None of these | ||
| Ans : D. The movements of the man are as shown in figure. Therefore, Man's distance from initial position A = AE = (AB + BE ) = (AB + CD) = (30 + 20 )metres = 50 metres. | |||
| 18. | Ramakant walks northwards. After a while, he turns to his right and a little further to his left. Fianlly, after walking a distance of one kilometre, he turns to his left again. In which direction is he moving now? | ||
|---|---|---|---|

| 19. | From his house, Lokesh went 15 kms to the North. Then he turned West and covered 10 kms. Then, he turned South and covered 5 kms. Fianlly turning to East, he covered 10 kms. In which directions is he from his house? | ||
|---|---|---|---|
| A. East C. North | B. West D. South | ||
| An : C. The movements of Lokesh are as shown as figure.( A to B, B to C, C to D and D to E ).Clearly, his final position is E which is to the North of his house at A. | |||
| 20. | Deepak starts walking staright towards east. After walking 75 metres, he turns to the left and walks 25 metres straight. Again he turns to the left, walks a distance of 40 metres straight, again he turns to the left and walks a distance of 25 metres. How far is he from the starting point? | ||
|---|---|---|---|
| A. 25 metres C. 50 metres | B. 35 metres D. 140 metres | ||
| Ans : B. The movements of deepak are as shown in figure. Clearly, EB = DC = 40m. Therefore Deepak's distance from the staring point A = (AB - EB ) = ( 75 - 40 )m = 35 metres. | |||
