• Question 1 of 5 1. Question If you are facing north-east and move 10 m forward, turn left and move 7.5 m, then you are a) north of your initial position b) south of you initial position c) 12.5 m from the initial position d) Both A and C Correct Answer: D Explanation Clearly, the narrator starts from A, moves towards north-east a distance of 10 m up to B, turns left (90 degree anti-clockwise) and moves 7.5 m up to C. Clearly, C lies to the north of A. Also , ΔABC is right-angled at B. So, AC2 = AB2 + BC2 = (10)2 + (7.5)2 = 100 + 56.25 = 156.25 √(156.25) = 12.5 Thus the narrator is 12.5 m to the north of his initial position. Hence, option D is correct Incorrect Answer: D Explanation Clearly, the narrator starts from A, moves towards north-east a distance of 10 m up to B, turns left (90 degree anti-clockwise) and moves 7.5 m up to C. Clearly, C lies to the north of A. Also , ΔABC is right-angled at B. So, AC2 = AB2 + BC2 = (10)2 + (7.5)2 = 100 + 56.25 = 156.25 √(156.25) = 12.5 Thus the narrator is 12.5 m to the north of his initial position. Hence, option D is correct
#### 1. Question
If you are facing north-east and move 10 m forward, turn left and move 7.5 m, then you are
• a) north of your initial position
• b) south of you initial position
• c) 12.5 m from the initial position
• d) Both A and C
Explanation
Clearly, the narrator starts from A, moves towards north-east a distance of 10 m up to B, turns
left (90 degree anti-clockwise) and moves 7.5 m up to C. Clearly, C lies to the north of A. Also ,
ΔABC is right-angled at B. So,
AC2 = AB2 + BC2 = (10)2 + (7.5)2
= 100 + 56.25 = 156.25
√(156.25) = 12.5
Thus the narrator is 12.5 m to the north of his initial position. Hence, option D is correct
Explanation
Clearly, the narrator starts from A, moves towards north-east a distance of 10 m up to B, turns
left (90 degree anti-clockwise) and moves 7.5 m up to C. Clearly, C lies to the north of A. Also ,
ΔABC is right-angled at B. So,
AC2 = AB2 + BC2 = (10)2 + (7.5)2
= 100 + 56.25 = 156.25
√(156.25) = 12.5
Thus the narrator is 12.5 m to the north of his initial position. Hence, option D is correct
• Question 2 of 5 2. Question One day Ravi left home and cycled 10 km south wards, turned right and cycled 5 km and turned right and cycled 10 km and turned left and cycled 10 km. how many kilometers will he have to cycle to reach his home straight ? a) 10 km b) 15 km c) 20 km d) 25 km Correct Answer: B Explanation Clearly, Ravi starts from home at A, moves 10 km south wards up to B, turns right and moves and 5 km up to C, turns right again and moves 10 km up to D and finally turns left and moves 10 km up to E. Thus his distance from initial position A = AE + DE = BC + DE = (5 + 10) km = 15 km Hence, option B is correct. Incorrect Answer: B Explanation Clearly, Ravi starts from home at A, moves 10 km south wards up to B, turns right and moves and 5 km up to C, turns right again and moves 10 km up to D and finally turns left and moves 10 km up to E. Thus his distance from initial position A = AE + DE = BC + DE = (5 + 10) km = 15 km Hence, option B is correct.
#### 2. Question
One day Ravi left home and cycled 10 km south wards, turned right and cycled 5 km and turned right and cycled 10 km and turned left and cycled 10 km. how many kilometers will he have to cycle to reach his home straight ?
Explanation
Clearly, Ravi starts from home at A, moves 10 km south wards up to B, turns right and moves and 5 km up to C, turns right again and moves 10 km up to D and finally turns left and moves 10 km up to E.
Thus his distance from initial position A = AE + DE = BC + DE = (5 + 10) km = 15 km Hence, option B is correct.
Explanation
Clearly, Ravi starts from home at A, moves 10 km south wards up to B, turns right and moves and 5 km up to C, turns right again and moves 10 km up to D and finally turns left and moves 10 km up to E.
