Question

How many positive odd integers less than 300 can be formed using the digits 0, 1,2,3,4?

Answer 1

If you are allowed to use a single digit multiple times like 11 or 33 then the answer is: 50

If you can only use those digits once, then the answer is: --->  26

The question is a bit opaque :)

The way the question is written, it should be 50, but 26 can be an answer if those digits are only used once.
