14. Og‘irligi bir kilogramm bo‘lgan mahsulotning narxi berilgan. Uning og‘irligi grammlarda kiritilsin va to‘lash zarur bo‘lgan pul miqdori chop etilsin.

using System;

namespace Misol_1

class Program
{
static void Main(string[] args)
{
decimal narx = 5000;
int ogirlik = 1000;
decimal pulMiqdori = narx / (decimal)ogirlik;
Console.WriteLine("1 gr uchun pul miqdori: " + pulMiqdori.ToString("C"));
int mahsulotOgirlik = 750;
decimal tolovMiqdori = pulMiqdori * mahsulotOgirlik;
Console.WriteLine(mahsulotOgirlik + " gr uchun to'lov miqdori: " + tolovMiqdori.ToString("C"));
}
}
}
14 Berilgan butun sonlar ichida uchtasi bir-biriga teng. Boshqalaridan farqli bo‘lgan sonning tartib nomeri chop etilsin.

using System;

namespace Misol_2

{
static void Main(string[] args)

int a1 = 5;
int a2 = 7;
int a3 = 5;
int a4 = 5;

14 O‘nlik yozuvida bir xil raqamlari bo‘lmagan uch xonali sonlar o‘sish tartibida chop etilsin (butun sonlarni bo‘lish amalidan foydalanilmasin).

using System;

namespace Misol_3

{
class Program
{
static void Main(string[] args)
{
for (int i =100;i< 1000; i++)
{
int firstDigit = i / 100;
int secondDigit = (i / 10) % 10;
int thirdDigit = i % 10;

if (firstDigit != secondDigit && firstDigit != thirdDigit && secondDigit != thirdDigit)

{
Console.WriteLine(i);
}
}
}

14 Tekislikda uchta to‘g‘ri chiziq tenglamalari bilan berilgan. Agar bu to‘g‘ri chiziqlar juft-jufti bilan kesishib, uchburchak hosil qilsa, shu uchburchak yuzasi hisoblansin.

using System;

double distanceAB;

double distanceAC;

double distanceBC;

double x1 = 1;

double y1 = 2;

Console.WriteLine("Uchburchak yuzasi: " + area);
