During the Qingming holiday , My nephew in primary school threw his math homework to me . I look at the title ：what？！ This is the topic of primary school ？

The title is like this ：

There is one less than 500 Three digits of abc, For this three digit number , A, B, C and d have the following words ：

nail ： This three digit number can be 2 to be divisible by 3 Time

B ： This three digit number can be 3 to be divisible by 2 Time

C ： This three digit number can be 7 to be divisible by

Ding ： The sum of the three digit numbers is 15

It is known that ： One of them lied , Excuse me, 2a+b+c=？

This question is not to use Python Is it solved ？

for a in range(1, 5):
    for b in range(0, 9):
        for c in range(0, 9):

            abc = a * 100 + b * 10 + c

            T1 = abc % 8 == 0 #  nail ：abc Can be 2 to be divisible by 3 Time 
            T2 = abc % 9 == 0 #  B ：abc Can be 3 to be divisible by 2 Time 
            T3 = abc % 7 == 0 #  C ：abc Can be 7 to be divisible by 
            T4 = a + b + c == 15 #  Ding ：abc The sum of all the numbers in is 15

            if T1 is True and T2 is True and T3 is True: # Suppose Ding lied ,  The conditions for a, B and C are established 
                print(' Ding lied ,abc=%s' % abc)
            elif T1 is True and T2 is True and T4 is True: # Suppose C lies ,  The conditions of Party A, Party B and Party D are established 
                print(' C lying ,abc=%s' % abc)
            elif T1 is True and T3 is True and T4 is True: # Suppose b lies ,  The conditions for meprodin are established 
                print(' B lying ,abc=%s' % abc)
            elif T2 is True and T3 is True and T4 is True: # Suppose a lies ,  The conditions for EPD are established 
                print(' A lie ,abc=%s' % abc)

loop + Judge , The steady ！

The final output answer is ：

B lying ,abc=168

I have a long sigh of relief , Finally, I made a good job ！ I almost thought I was “ also 㕛 A kind of ” It's going to overturn ！ incorrect ！ This is a math problem ？！ I use Python Tell him the answer , How can you understand ？！

Don't worry , I don't want to pull my hair away , hit “ 800 pages ” draft ！ Directly to the sister who is a math teacher , There is a specialty in this field ！ Code farmers knock code to solve problems , b. ！

The key! ！2022 year 4 month 24 Japan , Blue bridge cloud class will be launched The first 33 Phase building competition ——Python application ： Math problems that couldn't be solved in those years , Take you to unlock the darkness of childhood , Welcome to the challenge ！
