                      let the 5 quantities be a , b , c ,d ,and e

                      according to the question

     !st case-   a + b + c + d + e/5 = 6

                      a + b + c + d + e = 30              ...............(1)

    2nd case-  a + b + c/3 = 8
                     
                     a + b + c= 24                              ................(2)

                     putting eq 1 in eq 2
                 
                    24 + d +e = 30

                    d + e = 30-24
 
                    d + e = 6                                ..............(3)

              average of remaining two terms .i.e. d and e 
                 
                  d + e /2 

                putting eq (3)

                6/2= 3
           
             ans- 3
