Explanation

Step 1: S is placed first

Position 1 = S

Step 2: R immediately after S  

Position 2 = R

Step 3: Q after S

Q can be 3, 4, or 5

Step 4: P must stand before Q

So P comes somewhere before Q

Step 5: T not first

First is already S, so this is satisfied

Possible arrangement: S R P Q T or S R P T Q or S R T P Q

Correct Answer: R is second

Explanation

To determine the relationship, we can break down the family structure:

B and D are sisters: The problem states D is B's sister.

A is B's daughter: This makes B A's mother.

E is D's son: This makes D E's mother.

A and E's relationship: Since A's mother (B) and E's mother (D) are sisters, A and E are the children of siblings.

Therefore, A is the cousin of E.

Explanation

Six people A, B, C, D, E, F sit around a circular table facing center.

1. C is opposite A.  

2. E is opposite B.  

3. D is second to the left of C.  

4. A is second to the right of B.  

From 1: Place A and C opposite each other.  

From 2: Place B and E opposite each other.  

From 3: D is 2nd left of C.  

From 4: A is 2nd right of B.  

Arranging all conditions, the order clockwise is:  

B, A, D, C, E, F  

Check:  

A is 2nd right of B ✓  

C opposite A ✓  

D 2nd left of C ✓  

E opposite B ✓  

Now check neighbors of F: B and A.  

So F is sitting between B and A.

Start with 34 passengers.

8 get off → 34 − 8 = 26

16 get on → 26 + 16 = 42

Half of 42 get off → 42 ÷ 2 = 21 get off.

Remaining passengers = 42 − 21 = 21.

Explanation

Given:

• G is at the extreme right end → G = Position 7
• F sits exactly between C and G → C – F – G
  • Therefore: C = Position 5, F = Position 6, G = Position 7
• A sits third to the left of D → A = Position 1, D = Position 4
• B sits immediately to the right of A → B = Position 2
• E is not at either end → E = Position 3

Final Arrangement:
