    Q1): While purchasing certain items,
     a discount of 10% is offered if the quantity 
     purchased is more than 1000. If quantity and price per item 
     are input through the keyboard,
     write a program to calculate the total expenses. 

    <br><br>
    <input type="text" name="" id="qty" placeholder="enter quantity"><br><br>
    <input type="text" name="" id="price" placeholder="enter price per item">
    <button onclick="myFunction()">Check</button>

    <script>

        function myFunction(){
            var qty = document.getElementById('qty').value;
            var price = document.getElementById('price').value;

            alert(calculate(qty,price))
            
            
        }

        function calculate(qty,price){
            var amount = qty*price ;
            var dis = amount - (amount*10 /100);
            if( qty >=1000){
                return('your amount after discount of Rs: ' +dis)
            }
            else{
                return('your amount is ' +amount)
            }

        }
