These questions are based on the diagram given below showing four persons stationed at the four corners of a square piece of plot as shown :
Q. No. 1:
A starts crossing the plot diagonally. After walking half the distance, he turns right, walks some distance and turns left. Which direction is A facing now ?
From the original position given in the above figure, A and B move one arm length clockwise and then cross over to the corner diagonally opposite, C and D move one arm length anti-clockwise and cross over the corner diagonally opposite. The original configuration ADBC has now changed to :
Answer: A Hence, final configuration of ADBC has now CBDA. Where, A1, B1, C1 and D1 are original positions of A,B,c and D.... A2, B2, C2 and D2 are position after 1st movement of A,B,C and D. A3, B3,C3 and D3 are final positions.
Q. No. 3:
From the original position,B and D move one and a half length of sides clockwise and anticlockwise respectively. Which one of the following statements is TRUE ?
A :
B and D are both at the midpoint between A and C
B :
B is at the midpoint between A and C, and D is at the corner originally occupied by A.
C :
D is at the midpoint between A and C, and B is at the corner originally occupied by C.
Answer: A Hence, B and D are at the mid point between A and C.
Q. No. 4:
From the positions in the original figure, C and A move diagonally to opposite corners and then one side each clockwise and anti-clockwise respectively. B and D move two sides each clockwise and anti-clockwise respectively. Where is A now ?
A rat runs 20' towards East and turns right, runs 10' and turns right rum 9' and again turns to left, runs 5' and then turns left, runs 12' and finally turns to left and runs 6'. Now, which direction is the rat facing ?
Answer: B A and B are starting and finishing positions respectively of the rat. It is clear that B is facing North direction.
Q. No. 22:
Rakesh is standing at a point. He walks 20m towards the east and further 10m towards the South, then he walks 35m towards the West and further 5m towards the North, then he walks 15m towards the East. What is the straight distance in metres between his starting point and the point where he reached last ?
Ravi traveled 4km straight towards south. He turned left and traveled 6km straight, then turned right and traveled 4km straight. How far is he from the starting point ?
Answer: B B is the finishing point and is 10km from the point A. The aerial distance of A from B is 10km calculated as below : (AB)2 = (AD)2 + (DB)2 = 64 + 36 = 100 => AB = 10 km.
Q. No. 24:
B is to the South-West of A, C is to the East of B and South-East of A and D is to the North of C in line with B and A. In which direction of A is D located ?
