Answers
No car is parked in Slot 5 and Slot 5
- Slot 3 is blocked by Red Car (mentioned in question)
- Slot 2 is blocked by White Car (question 29 says)
- Slot 1 has Blue Car (condition 2 says that blue is parked nect to white)
- Remaining Slots - 4, 5 and 6.
- But as per condition 3, Green and Maroon can not be parked together. Thus, if Green is in Slot 4, Maroon is in Slot 6. If Green is in Slot 6, Maroon is in Slot 4.
- In all situations, Slot 5 is empty
None of the cars is parked in slot number 5 must be true if the white car is parked in slot 2
The maroon car cannot be parked in Slot 5

Solution:
29.
White (W) car is parked in slot 2 , The red (R) car must be parked in slot 3.
1 2 3 4 5 6
W R
The blue(B) car must be parked in the slot next to slot in which the white
car is parked Hence slot 1
1 2 3 4 5 6
B W R
The green car cannot be parked in a slot next to the slot in which the
maroon car is parked Hence Green (G) and Maroon (M) car can not be in 4
1 2 3 4 5 6
B W R G/M - M/G
None of the cars is parked in slot number 5 is Always True in this case
Hence option 4) None of the cars is parked in slot number 5
30.
The red (R) car must be parked in slot 3.
1 2 3 4 5 6
R
The blue (B) car must be parked in the slot next to slot in which the white (W) car is parked hence possible combinations are
1 2 3 4 5 6
B/W W/B R
1 2 3 4 5 6
R B/W W/B
1 2 3 4 5 6
R B/W W/B
The green car cannot be parked in a slot next to the slot in which the maroon car is parked Hence in case 1
1 2 3 4 5 6
B/W W/B R G/M - M/G
Hence Maroon is not parked in 1 2, 3 and 5
In remaining 2 cases Maroon is not parked in 3 and 5
1 2 3 4 5 6
R B/W W/B
1 2 3 4 5 6
R B/W W/B
Hence Maroon can not be parked in 3 and 5
From the given options 5 is the answer
The maroon car cannot be parked in Slot 5
option 4) Slot 5 is correct
