CAT 1998 — DILR Question 47
Linear ArrangementEasy
Passage / Data
Direction: Answer the questions based on the following information.
A, B, C and D are to be seated in a row. But C and D cannot be together. Also B cannot be at the third place.
If A is not at the third place, then which of the following options does C have?
Answer & solution
- A
The first place only
- B
The third place only
The first and third place only
- D
Any of the places
Solution
Since neither A nor B can be at 3rd place, this place has to be occupied by either D or C. And if either of them occupies this place, the other one has to occupy the 1st place (since D and C cannot be together).
Hence, C can only occupy either 1st or 3rd place.
