Assumption: The man hadn’t eaten salmon before he and his friend got stranded on the island.

When the fisherman offered him the dish he claimed to be salmon, the man believed him and consumed the dish. Later, when he ordered salmon at the diner, he expected a similar experience. But the dish – the real salmon – he was served got him stumped. He understood that the fisherman had lied – not only about the dish but about his friend’s death as well – the fisherman had killed his friend.  Thinking further, it is also possible that the ‘salmon dish’ the killer fisherman offered him might, in fact, have been his friend’s flesh (which he couldn’t have thought of earlier because he had no prior experience of salmon dish). That thought must have been more than enough to shatter his mind and drive him to suicide.

The sailor need NOT be a MAN.  The father of her son and the son himself can be on the boat, irrespective pf whether she’s there or not.

14, with 2 butts left.

One of the fathers and sons were the same person! There were only three persons forming a three-generation  sequence. The eldest of the three is the father of the second. The second one (who is son of the eldest), in turn, was the father of the youngest. The youngest, being the son of the second completes the team.

10, 15, 9, 20, and 12

Possible combinations (each dice):

1)  2, 5  (2 x 5 = 10)
2)  3, 5  (3 x 5 = 15 = 10 + 5)
3)  3, 3  (3 x 3 = 9 = 15 – 6)
4)  4, 5  (4 x 5 = 20 = 9 + 11)
5)  3, 4  (3 x 4 = 12 = 20 – 8)

It IS true that the answer is 5!

25 – 55 + (85 + 65)  = 120 ;
and
5! = 1 x 2 x 3 x 4 x 5 = 120…! 

To distribute 24L equally among 3, every person should get 8L each.

1. Fill 13L jar (The original 24L jar now contains 11 L)
2. Pour the water from the 13L jar to the 5L jar. There will be 8L left in the 13L jar,
3. Pour it to the 11L jar. With this, one person’s share is done.
4. Pour the contents of the 5L jar back to the 13L one. It will now have space for 8 more litres.
5. Fill the remaining space in the 13L jar from the quantity that remains in the 24L jar. Since that jar had 11L after Step 1, it will now have 3L. (11 – 8 = 3) left.
6. Fill the 5L jar from the 13L jar (which is now full after Step 4). Now, the 13L jar contains 8L. Second person’s share  done.
7. Pour the contents of the 5L jar (filled in step 6) to the 24L jar (which already holds 3L after step 5), thereby making it 8L. Sharing completed.

Probabilities of individual events are independent of each other and the outcome of the first  (or subsequent) events. Hence, the probability of the second child to be a girl will be 1/2 x 1/2 = 1/4

‘T‘ is the letter before U.

Even though one of the meanings of the word ‘before’ is somewhat similar to ‘in front of’, they can’t be used interchangeably.
