Question 71. Molly travelled from point A to point B which is 5 ft. He, then travelled 6 ft to his right and then turned to left and went 4 ft. Finally, he again went 6 ft to his left. How far is he from the point B now?
  1.    4 ft
  2.    10 ft
  3.    6 ft
  4.    5 ft
 Discuss Question
Answer: Option A. -> 4 ft
Answer: (a)
According to the question, the direction diagram will be as follows. Therefore, Required distance, BE = 4 ft.
Question 72. A man goes 5 km East from his office. He then takes left turn and walks 3 km. He again takes left turn and walks 5 km. How far is he starting point?
  1.    3 km
  2.    4 km
  3.    6 km
  4.    7 km
  5.    8 km
 Discuss Question
Answer: Option A. -> 3 km
Answer: (a)
According to the question, the direction diagram is as follows.
OB = CD = 5 km BC = OD = 3 km Therefore, Required distance, OD = 3 km.
Question 73. Hari travelled 17 km to the East, he turned left and went 15 km, he again turned left and went 17 km. How far is he from the starting point?
  1.    32 km
  2.    17 km
  3.    2 km
  4.    15 km
 Discuss Question
Answer: Option D. -> 15 km
Answer: (d)
According to the questions, the direction diagram will be as follows.
Now, AB = CD = 17 km and BC = AD = 15 km
Therefore, Required distance, AD = 15 km.
Question 74. A and B both are walking away from point 'X'. A walked 3 m and B walked 4 m from it, then A walked 4 m North of X and B walked 5 m south of A. What is the distance between them now?
  1.    9.5 m
  2.    9 m
  3.    16 m
  4.    11.40 m
  5.    10.40 m
 Discuss Question
Answer: Option D. -> 11.40 m
Answer: (d)
Required distance, AB = $√{(72 + 92)}$ = $√{130}$ = 11.40 m
Question 75. John travels 14 km westwards and then turns left and travels 6 km and further turns left and travels 26 km. How far is John now from the starting point?
  1.    $√180$ km
  2.    $√80$ km
  3.    $√100$ km
  4.    None of these
 Discuss Question
Answer: Option A. -> $√180$ km
Answer: (a)
According to the question, the direction diagram will be as follows.
AB = CE = 14 km
BC = AE = 6 km
CD = 26 km
ED = CD - CE = 26 - 14 = 12 km
Therefore, Required distance, AD = $√{(AE)^2 + (ED)^2}$ (by pythagoras theorem)
= $√{(62 + 122)}$ = $√180$ km
Question 76. Ram goes 15 m North, then turns right and walks 20 m, then again turns right and walks 10 m, then again turns right and walks 20 m. How far is he from his original position?
  1.    5
  2.    10
  3.    15
  4.    20
  5.    25
 Discuss Question
Answer: Option A. -> 5
Answer: (a)
DC = EB = 5 m
Therefore, Required distance = AE = AB + BE
= 10 + 5 m = 15 m.
Question 77. A boy rode his bicycle northwards, then turned left and rode one km and again turned left and rode 2 km. He found himself exactly one km west of his starting point. How far did he ride northwards initially?
  1.    1 km
  2.    2 km
  3.    5 km
  4.    8 km
  5.    10 km
 Discuss Question
Answer: Option B. -> 2 km
Answer: (b)
Clearly, the boy rode from A to B, then to C and finally up to D.
Since D lies to the west of A, so required distance = AB = CD = 2 km.
Question 78. A man leaves for his office from his house. He walks towards East. After moving a distance of 20 m, he turns South and walks 10 m. Then he walks 35 m towards the West and further 5 m towards the North. He then turns towards East and walks 15 m. What is the straight distance (in metres) between his initial and final positions?
  1.    0
  2.    5
  3.    15
  4.    Cannot be determined
  5.    None of these
 Discuss Question
Answer: Option B. -> 5
Answer: (b)
The movements of the man from A to F are as shown in Fig. 13
Clearly, DC = AB + EF. Therefore, F in line with A.
Also, AF = (BC - DE) = 5 m.
So, the man is 5 metres away from his initial position.
Question 79. Raj travelled from a point X straight to Y at a distance of 80 metres. He turned right and walked 50 metres, then again turned right and walked 70 metres. Finally, he turned right and walked 50 metres. How far is he from the starting point?
  1.    10 metres
  2.    20 metres
  3.    50 metres
  4.    70 metres
  5.    90 metres
 Discuss Question
Answer: Option A. -> 10 metres
Answer: (a)
The movements of Raj are as shown in Fig . 30.
(X to Y, Y to A, A to B, B to C).
Therefore, Raj's distance from the starting point = XC = (XY - YC)
= (XY - BA)
= (80 - 70) m = 10 m.
Question 80. A man walks 30 metres towards South. Then, turning to his right, he 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?
  1.    20 metres
  2.    30 metres
  3.    50 metres
  4.    60 metres
  5.    80 metres
 Discuss Question
Answer: Option C. -> 50 metres
Answer: (c)
The movements of the man are as shown in Fig. 25.
Therefore, Man's distance from initial position A.
= AE = (AB + BE) = (AB + CD)
= (30 + 20) m = 50 m.
