How to calculate: T and his sister J have a combined age of 48, J is twice as old as his sister, how old is J in C++

Answer 1

#include <iostream>

int main() {
    int age;
    
    // age + 2age = 48
    // 3age = 48
    // age = 48 / 3

    age = 48 / 3;

    std::cout << "J age = " << age << "\n";
    std::cout << "T age = " << age * 2;
}

 
 
/*
run:
 
J age = 16
T age = 32
 
*/
