    In Multipath inheritance, in order to remove duplicate set of records in child class, we Make base class as virtual base class.
    Suppose that we have two classes Test and Sports class. These classes are inherited from the Student base class. Therefore all the public and protected member of student class will be part of Test and Sports class. Again suppose that Result class is derived from Test and Sports class (Multiple Inheritance). So Result class has two copies of data member and member function of Student class. This situation will create problem. The solution of this problem is virtual base class. If we declare Student class as a virtual class while inheriting it, then only one copy will be inherited in Result class.
