Questions & Step-by-Step Solutions
In a linear arrangement of four people P, Q, R, and S, if P is sitting next to Q and R is sitting at one end, which of the following is a possible arrangement?
Step 1: Identify the people involved: P, Q, R, and S.
Step 2: Understand the conditions: P must sit next to Q, and R must be at one end of the arrangement.
Step 3: Since R is at one end, we can place R in the first position.
Step 4: Since P must sit next to Q, we can place P and Q in the next two positions.
Step 5: The only person left is S, who will take the last position.
Step 6: The arrangement is now R, P, Q, S, which satisfies both conditions.
