I made a simple modification for you.

Codes:

using System;

namespace ConsoleApp9
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Purchase a, b, c, d;
            Console.WriteLine("First purchase price and amount:");
            a = ReadL();
            Console.WriteLine("Second purchase price and amount:");
            b = ReadL();
            Console.WriteLine("Third purchase price and amount:");
            c = ReadL();
            Console.WriteLine("Fouth purchase price: and amount:");
            d = ReadL();

            //Processing
            Purchase Sum = new Purchase();
            Sum.price = a.price + b.price + c.price + d.price;
            Sum.amount = a.amount + b.amount + c.amount + d.amount;

            Purchase Average = new Purchase();
            Average.price = Sum.price / 4;
            Average.amount = Sum.amount / 4;

            Console.WriteLine("Average buying price={0},Average buying amount={1}", Average.price, Average.amount);

            Console.ReadKey();

            Purchase ReadL()
            {
                Purchase X = new Purchase();
                var inputs = Console.ReadLine().Split(' ');
                X.amount = Convert.ToDecimal(inputs[0]);
                X.price = Convert.ToDecimal(inputs[1]);
                return X;
            }
        }
        class Purchase
        {
            public decimal price { get; set; }
            public decimal amount { get; set; }
        }
    }
}

Output:
