How many times can you subtract the number 5 from 25?

Choose an answer

A.Five
B.Zero
C.Twenty
D.Once, because after you subtract 5 from 25 it becomes 20.
Hint: It's a 8-word phrase with 40 letters, starting with "O".

Answer

Once, because after you subtract 5 from 25 it becomes 20.

Why this is the answer

After the first subtraction, 25 is no longer 25, so you can never again 'subtract 5 from 25.'
