Answer 1

2 is the digit at the tens place of the sum of the four digit even numbers formed by using 7, 2, 9, 0 once only.

Step-by-step explanation:

By using 7, 2, 9, 0 we have to write four digit even numbers.

The numbers having 0 and 2 in unit place is called even numbers.

So, the even numbers are 7920, 7290, 9720, 9270, 2790, 2970, 7902, 7092, 9702, 9072.

Sum = 7920 + 7290 + 9720 + 9270 + 2790 + 2970 + 7902 + 7092 + 9702 + 9072

Sum = 73728

Digit at tens place of  73728 is 2.

Hence, 2 is the digit at the tens place of the sum of the four digit even numbers formed by using 7, 2, 9, 0 once only.
