Question

Misty is fond of pokemons and likes to collect pokemon cards. She has P pokemon cards with her at present. She wants to have a particular number of cards on the Dth day. Her friend Ash is ready to help her to achieve the number. Ash will provide her N cards daily so that a day before the Dth day, she will have the required number of Pokemon cards.

Answer 1

Assuming that first line will have the number of test cases followed by each line having three space separated integers P, N and D, we can get the total number of cards a day before Dth day as follows:

In python

t = int(input())
for i in range(t):
    p, n, d = map(int, input().split())
    total = p + n*(d-1)
    print(total)

In c++

#include <iostream>
using namespace std;

int main() {
    int t;
    cin >> t;
    
    for(int i=0; i<t; i++) {
        int n, p, d, total;
        cin >> p >> n >> d;
        total = p + (n*(d-1));
        cout<<total<<"\n";
    }
}

In java

import java.util.*;

public class MyClass {
    public static void main(String args[]) {
        Scanner sc = new Scanner(System.in);
        int t = sc.nextInt();
        for(int i = 0; i<t; i++) {
            int p = sc.nextInt();
            int n = sc.nextInt();
            int d = sc.nextInt();
            
            int total = p + (n*(d-1));
            System.out.println(total);
        }
    }
}
