集邮

 

集邮爱好者把所有的票存放在3个集邮册中,在A册内存放全部的十分之二,在B册内存放不知道是全部的七分之儿,在C册内存放303张邮票,问这位集邮爱好者的集邮总数是多少?以及每册中各有多少邮票?

 

int x, y, z, i, sum;
for (i = 0; i <= 5; i++)
{
    if (10605 % (28 - 5 * i) == 0)
    {
        sum = 10605 / (28 - 5 * i);
        x = 2 * sum / 10;
        y = 5 * sum / 7;
        z = 303;
        cout << "sum:" << sum << " ";
        cout << "x:" << x << " ";
        cout << "y:" << y << " ";
        cout << "z:" << z << " ";
    }
}
