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
Correct
Correct Option: D
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
AC = (156.25) m = 12.5m
Thus the narrator is 12.5 m to the north of his initial position.
Hence, option D is correct.
Incorrect
Correct Option: D
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
AC = (156.25) m = 12.5m
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 ?
Correct
Correct Option: B
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
Correct Option: B
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.

Question 3 of 5
3. Question
Kunal walks 10 km towards North. From there he walks 6 km towards South. Then, he walks 3 km towards East. How far and in which direction is he with reference to his starting point?
Correct
Correct Option: D
Clearly, Kunal moves from A 10 km north-wards up to B, then moves 6 km southwards up to C, turns towards East and walks 3 km up to D. Then, AC = (AB – BC) = (10 – 6) = 4 km. So, Kunal’s distance from the starting point A.
(AD)2 = (AC2 + CD2) = (4)2 + (3)2 = 5 km.
Also, D is to the North-east of A.
Hence, option D is correct
Incorrect
Correct Option: D
Clearly, Kunal moves from A 10 km north-wards up to B, then moves 6 km southwards up to C, turns towards East and walks 3 km up to D. Then, AC = (AB – BC) = (10 – 6) = 4 km. So, Kunal’s distance from the starting point A.
(AD)2 = (AC2 + CD2) = (4)2 + (3)2 = 5 km.
Also, D is to the North-east of A.
Hence, option D is correct
