Input is in stdin in format (3 4 5 6), output is left on stack:

T~dqZ*S1 5r]%{U*}/b+

Waiting for a response from the original poster about the output format. Since input is specified as "whatever you like", I am going to assume that my input can be an array on the top of the stack. Now takes input on stdin.

Explanation:

T~                            Get input from stdin and evaluate
  dqZ*                      Duplicate, get minimum, and multiply that by 10
      S1 5r]                Swap (so array is on top), push range 1-5 exclusive, and rotate
            %{U*}/          Zip arrays together, and multiply each pair
                  b+P       Get the sum of that, add the common minimum, and print
