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.
