Here is the given situation!
Well, there are 2 possibilities of answer depending on what combination of hats Man 2 & Man 3 are wearing. One thing is sure Man 4 has least chance for getting what he is wearing. His crime must be the most serious one!
Case 1 : If Man 2 & Man 3 wearing same color of hat.
In this case, Man 1 would immediately come to know that he is wearing opposite color of hat & would shout out. In simple words, if Man 2 & Man 3 wearing WHITE (or BLACK) hats, then Man 1 & Man 4 must be wearing BLACK (or WHITE) hats. Since there is no chance for Man 4 to see Man 2 & Man 3 but Man 1 could see Man 2 & Man 3, he must be first to know color of hat he is wearing.
Case 2 : If Man 2 & Man 3 wearing hats of different color.
Now here Man 2 has to be very intelligent (like the reader as he has chosen to read this further). In this case, there is no way for Man 1 to come at any conclusion as there might be WHITE or BLACK hat on his head. After waiting for a while Man 2 has to apply some logic & should think this in his mind.
'Since Man 1 is not shouting he must be unsure with color of his hat. He would be sure only in case if I & Man 3 wearing same color of hats. Since he is unsure; the color of my hat must be opposite of Man 3's hat.'
Now the judge if he is honest would put criminal with least serious crime at number 1 (or & 2) same color (or different) hats on Man 2 & Man 3.
This is an unusual paragraph. I’m curious as to just how quickly you can find
out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it! It is highly unusual though. Study it and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out. Try to do so without any coaching.
This is certainly unusual!

What was the unusual?
Well, you will not find anything wrong grammatically there neither you won't find any spelling mistake in entire paragraph. The letter 'e' is one of the most common letter used in English language. If you carefully observe the letter 'e' never appears in the paragraph.
I was visiting a friend one evening and remembered that he had three daughters. I asked him how old they were. “The product of their ages is 72,” he answered. Quizzically, I asked, “Is there anything else you can tell me?” “Yes,” he replied, “the sum of their ages is equal to the number of my house.” I stepped outside to see what the house number was. Upon returning inside, I said to my host, “I’m sorry, but I still can’t figure out their ages.” He responded apologetically, “I’m sorry, I forgot to mention that my oldest daughter likes strawberry shortcake.” With this information, I was able to determine all three of their ages. How old is each daughter?

How it was asked to find with some clues?
The product of their age is 72; so possible combinations are,
3 x 3 x 8 = 72 3 + 3 + 8 = 14
2 x 6 x 6 = 72 2 + 6 + 6 = 14
2 x 2 x 18 = 72 2 + 2 + 18 = 22
2 x 3 x 12 = 72 2 + 3 + 12 = 17
2 x 4 x 9 = 72 2 + 4 + 9 = 15
3 x 4 x 6 = 72 3 + 4 + 6 = 13
If any of last 4 combinations was correct then I would have come to know ages of daughter straightaway as their sum is unique. So friend's house number as he must have told must be 14. That's why I was uncertain with the correct combination as they are appearing twice.
In next clue, he indirectly suggest he has only 1 oldest daughter. So 2,6,6 is eliminated as in that case he would have 2 oldest daughters.
So the correct combination is 3,3,8. That means he had oldest daughter of age 8 & younger twins.

What was the challenge?
1. First 2 boys of 50 pounds should cross the river.
2. One of them should bring back the boat at other end.
3. A boy with 100 pounds should carry himself across the river with boat.
4. Other boy of 50 pounds waiting across the river now should bring back the boat again.
5. Now both boys of 50 pounds now should cross the river.
