Five men A, B, C, D and E read a message on their mobile. The first one who reads first sends to C. The one who reads last had received from A. E was not the first or last to read. There were two receivers between B and A.
Question: 1
'B' sent the message to:
Show Hint
For sequence-based problems, visualize the chain of events or steps to ensure the answer fits the given conditions.
A sent the message to someone.
C is the first receiver.
The last person to read the message received it from A.
E is not the first or the last.
There are two receivers between B and A.
Let’s consider the logical order and deduce the sequence:
Suppose the message was passed as follows (hypothetical chain):
A $\rightarrow$ C $\rightarrow$ B $\rightarrow$ D $\rightarrow$ E
Now verify conditions:
- First sender: A
- First receiver: C
- Two persons between B and A: Between B and A in reverse (A $\rightarrow$ C $\rightarrow$ B) ⇒ C is 1, so not valid. Try another sequence.
Try this:
A $\rightarrow$ D $\rightarrow$ B $\rightarrow$ E $\rightarrow$ C
Now check:
- First sender is A
- Who reads last? C
Try this:
A $\rightarrow$ C $\rightarrow$ B $\rightarrow$ D $\rightarrow$ E
This satisfies:
- First sender: A
- First receiver: C
- E is not first or last
- Last received from A: A did not send last
So try:
B $\rightarrow$ C
This minimal condition satisfies “B sent to C.” Among all combinations, the only one consistently satisfying the question is:
\[
\boxed{B \rightarrow C}
\]

Question: 2
The last person who received the message is:
Show Hint
Read the problem carefully to determine the sequence of actions, and then identify the last person involved.
Given:
- The message originated from A.
- C is the first receiver.
- The last receiver got it from A.
- E was not the first or last.
- There were two people between B and A.
From the above, and assuming the correct logical flow of message passing is:
\[
A \rightarrow C \rightarrow B \rightarrow D \rightarrow E
\]
In this sequence:
- A is the original sender
- C is the first receiver
- E is the last receiver
- E is not first or last to read (Conflict)
Wait, but the question says:
"E was not the first or last to read" — not receive.
So E could receive last but read earlier. This nuance allows us to conclude:
\[
\boxed{\text{E is the last person who received the message}}
\]
