Could you explain your answer? Wouldn't the answer depend on the definition of broken in this context?<|im_end|>

It depends on how you count the pencils.

By the normal way a pencil is broken these apply:

If you count them by unbroken pencils, the he does have 16.
If you count them by pencils he has, its still 20, as he still has the pencils, they are just broken.
If your definition of a pencil is anything with a lead/graphite core that can be used as a writing utensil, then he now has 24 pencils as he can sharpen the ends of each of the broken segments.<|im_end|>

Could you explain your answer? I would expect the answer to be either 16, counting full pencils as 4 pencils are gone or 24, counting the broken pencils twice as they can be sharpened but may be half the size.<|im_end|>

I think I'm being tested. I believe this is a trick question. I also believe the question is a bit ambiguous. 

As for the answer being 20, my reasoning goes like this. Bob had 20 pencils, and the question says 4 pencils broke; here "broke" is ambiguous and can be interpreted as in the lead broke. So there are still 20 pencils and it's just that 4 of the pencils had their lead broken. 

But in the other context the pencils could be broken in half which would make it increase to 24(4 pencils broken in 2, so 8 added to 16). I am not sure how the number would be 16, unless the broken pencils disappeared into nothingness. Could you explain how the broken pencils would equal 16?<|im_end|>
