using namespace std;

int main()

{

int x,y,z=0;

cout<<"please enter x:";

cin>>x;

cout<<" ";

cout<<"please enter y:"<<endl;

cin>>y; cout<<" ";

z=x+y;

cout<<"the value of z is:"<<z<<endl;

int mean=(x+y+z)/3;

cout<<"the mean of x,y and z is:"<<mean<<endl;

return 0;

}

Q2.ans-

#include<iostream>

#iinclude<stdlib.h>

using namespace std;

int main()

{

int price,quantity,tax;

cout<<"please enter the price without tax of 1kg of tomato:";

cin>>price;

cout<<" ";

cout<<"please enter number of kilogram:"<<endl;

cin>>quantity; cout<<" ";

cout<<"please enter the tax in percent unit:";

cin>>tax; cout<<" ";

int z=(price * quantity); //total cost of tomatao without tax

int totalcost=((100+tax)*z)/100; //total cost including tax
