You need to learn to Read The Fine Manual

I have provided an example of a way to execute the procedure that you have provided. Below that I have also provided a simpler example using a function instead of a procedure.

-- using procedure that you provided:
SCOTT@orcl_12.1.0.2.0> CREATE OR REPLACE TYPE new_type2 AS OBJECT
  2    (title	   VARCHAR2(12),
  3  	author	   VARCHAR2(40),
  4  	price	   number(5,2),
  5  	stock_qty  Number(12),
  6  	Member	   procedure new_discount1);
  7  /

Type created.

  6  	 netprice  number(8);
  7    BEGIN
  8  	 IF title = 'science' THEN
  9  	   discount := round(30*price/100);
 10  	   netprice := price-discount;
 11  	   dbms_output.put_line('the net price is :'||netprice);
 12  	 END IF;
 13  	 IF title = 'social' THEN
 14  	   discount := round(40*price/100);
 15  	   netprice := price-discount;
 16  	   dbms_output.put_line('the net price is :'||netprice);
 17  	 END IF;
 18    END new_discount1;
