Solutions for Questions 1 to 3: Analysis for the set

All the cabins are in the same row, so we can assign different positions and try to figure out a combination that satisfies all the conditions.

We know that: S2 _ S5

This shows that S2 can only occupy position 1 or 2 or 3

Also, we can say that section S5 can occupy position 3 or 4 or 5

We also know that the following order:

S3 S1 S2

There are two possibilities now

Adding the above case, we get the following order:

S3 S1 S2 S4 S5

Answer 1: (d)

Fifth cabin belongs to ‘S5’ section

Answer 2 : (b)

Section S4 belongs to cabin 4

Answer 3 : (b)

We can see the from above order that Group G2, that is sections S3, S4 and S5 occupy cabin numbers 1, 4 and 5.
