Answer:
Required sum = 133,068
Step-by-step explanation:
The given digits are 7 , 9 , 1 , 3
- We are not allowed to repeat any of these digits. So we can use each digit only once.
Total ways = 4 ! = 24
So we can make 24 such numbers
So there are 24 4-digit number that we can make using 7 , 9 , 1 , 3 using each digit only once.
Required sum = 7193 + 7139 + 7913 + 7931 + 7319 + 7139 + 9137 + 9173 + 9371 + 9317 + 9731 + 9713 + 1973 + 1937 + 1793 + 1739 + 1379 + 1397 + 3179 + 3197 + 3791 + 3719 + 3971 + 3917
Required sum = 133,068
I hope it will help you.
