Union may have collection of different datatypes. so, it allocates the memory of the largest data type.
Ex:
union xyz{
int x;
float y;
double z;
};
It allocates only 8 bytes for whole. Agree?

Rajadurai is wrong.
Union not allocate for large memory size.
It allocate the last overrided value Whether it is large or small

At first union stores large value into memory, so we Will get 20 as output.
