All But Seven Sheep Were Killed By Storm How Many Died

A shepherd had 17 sheep. All but seven died. How many was he left with?

Answers:

The answer is 7 becaues if you look closely at the sentence “All but seven” you could find that the sentence is equivalent to “All the sheep died except seven sheep” which means that remaining 7 sheep aren’t died which concludes that only 7 sheep are left with the Shepherd.
