The Classes of the Distribution are,

9.5-14.5, 14.5-19.5, 19.5-24.5, 24.5-29.5, 29.5-34.5

Explanation:

The Upper Boundary Point (UBP) of the First Class is given by the Average of (1) the UBP of the 1^(st) Class and (2) the Lower Boundary Point of the 2^(nd) Class.

In our case, it is (14+15)/2=14.5.

Proceeding on the same lines, the Classes of the Distribution are,

9.5-14.5, 14.5-19.5, 19.5-24.5, 24.5-29.5, 29.5-34.5
