Time to go shopping!
Everything in the store has been discounted by 20%.
You are given a program that takes the price of an item as input. Complete the program so that it outputs the discounted price to the console.
Input 1 = 150
Input 2 = 100
Input 3 = 1500

Answer 1

Don't pass Hard Code value as input.
Also it's JavaScript not Java.
Here is right solution
function main() {
var oldPrice = parseInt(readLine(), 10)
var discount = oldPrice - oldPrice * 20 / 100;
console.log(discount);
}
