Answer:

25

Step-by-step explanation:

Positive integers less than 250 are 1, 2, 3, ..., 248, 249.

Positive multiples of 5 that are not multiples of 10 are integers than end in 5.

5, 15, 25, 35, ...

In each group of 10 consecutive integers, 1 through 10, 11 through 20, etc. there is one integers ending in 5. From 1 to 250, there are 25 groups of 10 consecutive integers, so there are 25 integers that end in 5.

Answer: 25
