Question

- P, Q, R, S and T are five speakers who have to speak on a particular day, not
necessarily in the same order. R is neither the first nor the last speaker. There
are exactly three speakers after S and exactly three speakers ahead of T. If P
can speak with the content refering to Q's speech, then who is the last speaker
to speak?​

Answer 1

Answer:

T

Step-by-step explanation:

the sequence can possible in two ways

1. SQPRT

2. QSRTP

so, the answer according to first sequence is T

and if we consider second sequence then the answer is P

Answer 2

P is the last speaker to speak.

• From the given information, we know that R speaks 2nd, 3rd, or 4th.
• Since there are exactly three speakers after S, S is the 2nd speaker.
• Similarly, T is the 4th speaker.
• So, R is the 3rd speaker.
• Now, since P can refer to Q's speech, Q spoke before P.
• So, Q speaks first and P speaks last.
• The sequence becomes Q, S, R, T, P.
