**Riddle**: If you solve this, you are observant. mr. smith had 4 daughters. each daughter had 4 brothers. how many kids does mr. smith have?

**Answer**: Well! On the off chance that we imagine that ‘had’ be supplanted with ‘have’, at that point Mr. Smith have five kids.

Accepting the inquiry as a right one, we presume that one chance emerges. We can say that Mr. Smith has {no children} now.
