Math.min을 사용하면 아래처럼.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	static int min(int a, int b){
		return a<b ? a:b;
	}
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		System.out.print(min(Integer.parseInt(br.readLine()), min(Integer.parseInt(br.readLine()),
				Integer.parseInt(br.readLine()))) + min(Integer.parseInt(br.readLine()),
				Integer.parseInt(br.readLine())) - 50);
	}
}

min을 함수로 정의해서 사용.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	static int min(int a, int b){
		return a<b ? a:b;
	}
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		System.out.print(min(Integer.parseInt(br.readLine()), min(Integer.parseInt(br.readLine()),
				Integer.parseInt(br.readLine()))) + min(Integer.parseInt(br.readLine()),
				Integer.parseInt(br.readLine())) - 50);
	}
}
