Reasoning PYQs

Persons: A, B, C, D, E, F, G, H, I, J and K.

1. There are two people sitting between A and B.
2. G is the immediate neighbor of I and B.
3. I and A are not immediate members.
4. The number of persons between A and G is the same as the number of persons between K and A.
5. There is one person between H and F. H is not a immediate member of I and K.

6.There are three people between H and D. One of the neighbors of H is C. 7. E and J are immediate neighbors. 8. J sits to the immediate left of E.

So, Case 1, Case 2, Case 1B, Case 2B is invalid. 9. E and A are not immediate neighbors.

So. Case 2A is invalid.

The final arrangement is,

I. A sits second to the right of C.

II. Odd number of persons sit between A and I when counted from the left of A.

III. Immediate neighbors of A are H and J.

Hence, Both II and III are false statements.

Persons: A, B, C, D, E, F, G, H, I, J and K.

1. There are two people sitting between A and B.
2. G is the immediate neighbor of I and B.
3. I and A are not immediate members.
4. The number of persons between A and G is the same as the number of persons between K and A.
5. There is one person between H and F. H is not a immediate member of I and K.

6.There are three people between H and D. One of the neighbors of H is C. 7. E and J are immediate neighbors. 8. J sits to the immediate left of E.

So, Case 1, Case 2, Case 1B, Case 2B is invalid. 9. E and A are not immediate neighbors.

So. Case 2A is invalid.

The final arrangement is,

Hence, nine persons sit between K and D when counted from the right of K.

1) Sagar starts walking from his office in the South direction and walks for 5 km, from here he takes a left turn to reach the coffee shop which is 4 km away. From the coffee shop, he takes a left turn and walks for 1 km, and finally takes a right turn to reach the park which is 3 km away.

2) Anurag starts walking in the South direction and walks for 4 km, and then takes a left turn to reach the car stand which is 2 km. From the car stand, he takes a left turn and walks for 6 km and then takes right turn and walks 2 km and takes right turn and walks 2 km and then again takes left turn and walks 3 km and then takes right turn and walks for 4 km to reach the park.

By merging all the diagrams, the final diagram is:

Since Sagar and Anurag start from the same office (point A)

The shortest distance between the office and the car stand:

By using Pythagoras theorem:

(Hypotenuse)2  = (Perpendicular)2 + (Base)2

(Hypotenuse)2 = (4)2  + (2)2 

(Hypotenuse)2  = 16 + 4

Hypotenuse = √20

Hence, the shortest distance between the office and the car stand is √20 Km.

1. Sagar starts walking from his office in the South direction and walks for 5 km, from here he takes a left turn to reach the coffee shop which is 4 km away. From the coffee shop, he takes a left turn and walks for 1 km, and finally takes a right turn to reach the park which is 3 km away.

2. Anurag starts walking in the South direction and walks for 4 km, and then takes a left turn to reach the car stand which is 2 km. From the car stand, he takes a left turn and walks for 6 km and then takes right turn and walks 2 km and takes right turn and walks 2 km and then again takes left turn and walks 3 km and then takes right turn and walks for 4 km to reach the park.

By merging all the diagrams, the final diagram is:

Since Sagar and Anurag start from the same office (point A)

The total distance between Coffee shop to Park = 1 km + 3 km = 4 km

Hence, the total distance between the Coffee shop to Park is 4 km.

1. Sagar starts walking from his office in the South direction and walks for 5 km, from here he takes a left turn to reach the coffee shop which is 4 km away. From the coffee shop, he takes a left turn and walks for 1 km, and finally takes a right turn to reach the park which is 3 km away.

2. Anurag starts walking in the South direction and walks for 4 km, and then takes a left turn to reach the car stand which is 2 km. From the car stand, he takes a left turn and walks for 6 km and then takes right turn and walks 2 km and takes right turn and walks 2 km and then again takes left turn and walks 3 km and then takes right turn and walks for 4 km to reach the park.

By merging all the diagrams, the final diagram is:

Since Sagar and Anurag start from the same office (point A)

Hence, the final position is in the South-East direction with respect to the initial position.
