Answer 1

We can use Digit 1 , 3 times in a simple addition that has 12 as its total

Step-by-step explanation:

we must use the same single digit 3 times in a simple addition that has 12 as its total.

Very simple calculation is

4 + 4 + 4 = 12

but we can not use 4 , 3 , 9 & 2

Hence we have to combine Digits to make number

as resultant is 12

Hence only possible combination of digit is 1

Hence

11 + 1  = 12

We can use Digit 1
