    The number must be 30.

    Step-by-step explanation:

    The mystery number is less then 40.

    You say its name when you start at 3 and count by 3s. This means that it is a multiple of 3.

    You say its name when you start at 5 and count by 5s. This means that it is a multiple of 5.

    The only two numbers that are multiples of 3 and 5 and less than 40 are 15 and 30.

    Since we have been told that the number is not 15, the number must be 30.
