What does remaining number of ducks and number of remaining ducks mean?

Question

A farmer has 60 ducks. He sold 40 ducks. What is the remaining number of ducks?

The remaining number of ducks = 60 - 40 = 20

Number of remaining ducks = 60 - 40 = 20

Does both the phrase remaining number of ducks and number of remaining ducks means remaining ducks? Thanks a lot.

Answer 1

IF each duck had a number, maybe tattooed on it or on a tag hung around its neck, and 40 ducks that were sold had the number 2 and the remaining ducks had a 3 on their necks, then

the remaining number of the ducks would be 3

while the number of remaining ducks = 20

Otherwise, in any other context, the two phrases appear to mean the same thing
